1.1 Criteria for publication
The following types of papers will be considered:
Full research papers, which must represent a significant development in the particular field of analysis and are judged on the criteria of (i) originality and quality of scientific content, (ii) contribution to our existing knowledge, and (iii) appropriateness of length to content of new science. The Analyst strongly discourages papers reporting the application of routine/well established analytical procedures unless they contain chemical principles or applications of exceptional novelty. Minor enhancement in sensitivity or selectivity of a technique is not normally sufficient to merit publication in the journal. Although short articles are considered, the RSC strongly discourages fragmentation of a substantial body of work into a number of short publications. Unnecessary fragmentation will be a valid reason for rejection of manuscripts.
Communications, which must report preliminary research findings that are particularly novel/original, of immediate interest, are likely to have a high impact on the analytical science community and therefore rapid publication is desirable. Communications receive priority treatment and are published within 8 weeks of receipt. Ideally, each communication should be followed by a full research paper in The Analyst, Journal of Analytical Atomic Spectrometry, Journal of Environmental Monitoring, Lab on a Chip or another appropriate primary journal. Authors should provide at the time of submission a short paragraph explaining why their work justifies urgent publication as a communication.
Critical Reviews, which must be a critical evaluation of the existing state of knowledge on a particular facet of analytical science. Original work may be included. Simple literature surveys will not be accepted for publication. Potential review writers should contact the Managing Editor before embarking on their work.
Tutorial Reviews, which are review articles that are written to be of relevance to both the expert or someone new to the field, with a view to informing the reader of the most recent important developments in a specific area of analytical science (i.e., those not yet available in teaching texts) and give an indication of the author's view on where future developments might lead. Potential review writers should contact the Managing Editor before embarking on their work.
Other I-Section articles. Potential writers should contact Prof M Thompson (Scientific Editor, I-section) before embarking on their work.
Further information regarding criteria for publication in The Analyst can be found in a special editorial, "Expectations for the quality and originality of articles submitted to The Analyst".
1.2 Submission of articles
Microsoft Word article templates are available and instructions on their use can be downloaded. Please note that use of the templates is optional. Authors who decide not to use the template, should prepare their typescript in double spacing, single column format, with tables and figures appearing at the end of the text. Copies of any related, relevant, unpublished material and raw data should be made available on request. Authors may also recommend potential reviewers for their paper.
The Analyst only has space to publish three out of every ten submissions it receives. In order for a manuscript to be acceptable for The Analyst, it must report significant advances in analytical science, as reflected in its originality, scientific quality and contribution to knowledge. At the time of submission, authors should provide a short but explicit letter of justification for publication in The Analyst. The emphasis should be on why the work is considered to be original and novel, and why the research will be of interest to the analytical community at large. The justification will be passed on to the referees to aid them in making their recommendations.
1.2.1 Electronic manuscript submission
Electronic manuscript submission is preferred. Articles may be submitted to the appropriate Editor using the RSC file-upload service. Authors should send a PDF version of the manuscript as a single file (containing text, tables and figures). This file will be used for online refereeing where possible. (A Microsoft Word file may alternatively be supplied but is unlikely to be suitable for online refereeing). Manuscripts sent by file upload will be acknowledged by e-mail. Authors should contact the Editorial Office if they have not received an acknowledgement within 5 working days. When submitting electronically, authors will not be required to send a printed copy of the manuscript separately.
1.2.2 Manuscript submission by mail
Three copies of text and illustrations should be sent to: The Managing Editor, The Analyst, The Royal Society of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge CB4 0WF, tel +44 (0)1223 420066, fax +44 (0)1223 420247; or directly to the North American Editor, and a further copy retained by the author.
1.2.3 North American Editor
Papers from the Americas can be submitted by regular mail or, preferably, electronically using the RSC file-upload service to Professor Luis A Colón, Department of Chemistry, SUNY University at Buffalo, 578 Natural Sciences Complex, Buffalo, NY 14260-3000, USA, tel (716) 645 6800 Ext 2143, fax (716) 645 6963, Email lacolon@buffalo.edu. These papers will usually be refereed in North America.
1.3 Ethical Guidelines for Publication in Journals and Reviews
One of the foundations of the scientific profession is the acceptance by its members of a 'code of conduct' which outlines desired behaviour and obligations of members of the profession to each other and the public. Such a code of conduct seeks to maximise the benefits of science to society and the profession.
The publication of scientific research in journals is one of the fundamental ways in which the Royal Society of Chemistry (RSC) serves the chemical science communities. Central to this service are certain responsibilities that editors, authors and referees have to maintain the high ethical standard relating to the publication of manuscripts in the journals published by the RSC. These responsibilities are outlined in the following document.
1.4 Conflict of interest
Author affiliations, sources of support and commercial associations must be listed in the manuscript, and any other potential conflicts of interest must be acknowledged or disclosed to the Editor in the covering letter at the time of submission. Such information is held in confidence while the paper is under review and does not influence the editorial decision. Guidance notes on declaring a ‘Conflict of interest?are available here. |

The Editorial Office will acknowledge receipt of a contribution for consideration immediately by e-mail (if an appropriate e-mail address has been supplied). The acknowledgement will indicate the paper reference number assigned to the contribution. Authors are particularly asked to quote this number on all subsequent correspondence. Correspondence will be sent by Email where possible.
2.1 Peer review
Each manuscript deemed suitable for consideration as a submission will be reviewed by at least two referees, whose names are not disclosed to the authors. The referees' reports constitute recommendations to the appropriate Editor, who is empowered to take final action on manuscripts submitted. The Editor is responsible for all administrative and executive actions, and is empowered to accept or reject papers. This decision and relevant comments of the referees are communicated to the author. Differences of opinion are mediated by the Editor, possibly after consultation with further referees, or by the Editorial Board. It is the Editor's duty to see that, as far as possible, agreement is reached between authors and referees; although the referees may need to be consulted again concerning an author's reply to comments, further refereeing will be avoided as far as possible.
Manuscript revision. Electronic submission of the final version is preferred using the RSC file-upload service. Revised manuscripts should be sent in original file format (i.e., a native file rather than a PDF). Revised manuscripts should be accompanied by an itemised list of the changes made and the response to the referees' comments. Alternatively, two copies of the revised manuscript plus the itemised list and response to the referees should be submitted by mail.
Rejection. When rejection of a paper is recommended, the Editor informs the author. Authors have the right to appeal to the Editorial Board if they regard a decision to reject as unfair.
Acceptance. Authors will receive formal notification when papers are accepted for publication.
Detailed refereeing policy and procedure is available as a PDF document.
2.2 Proofs
PDF proofs for correction are sent by Email when possible. The Email address to which proofs are to be sent should accompany the paper. Please note that authors are responsible for the final proof-reading of manuscripts. It is imperative that authors check the proofs very carefully. Particular attention should be paid to numerical data both in the tables and text. Proof corrections should be returned to the Editorial office within 4 days of receipt (by Email, fax, first class mail, air mail, or express mail). All corrections should be sent at the same time. Papers are published as Advance Articles on the web as soon as possible after proof corrections are received from the authors. Late corrections cannot be incorporated after publication of the Advance Article.
An author may be required to pay the cost of any extensive changes made by him/her at proof stage (other than the correction of printer's errors). So far as possible, essential changes should be made without altering the length of the text, or at the end of a paragraph. The standard signs for proof correction set out in British Standard BS5261: Part 2 (1976) may be used: these are conveniently summarised in the pamphlet "Authors' alterations cost money and cause delay...", which can be purchased from the British Printing Industries Federation (11 Bedford Row, London, UK, WC1R 4DX). However, the author may prefer simply to put a line through the incorrect characters and write the correct version in the margin. Corrections should be made in ink, clearly and without ambiguity, and any queries from the printer and editorial staff on the manuscript, proof or query sheet should be answered fully. Alternatively, corrections can be sent by Email, in list format, clearly stating the page, paragraph and line number alongside each correction.
2.3 Reprints
The corresponding author will receive an electronic reprint (in PDF format) after publication. Authors may print and distribute hardcopies of their article on demand. Authors may also send the electronic file to individuals, as one would send a printed reprint. However, the electronic file may not be distributed via an email listserver and it may not be placed on any web site.
2.4 Copyright and permissions
The Analyst is copyright of the Royal Society of Chemistry and apart from fair dealing for the purposes of research or private study, or criticism or review, as permitted under the Copyright, Designs and Patent Act 1988 no part of the journal may be reproduced without prior permission in writing from the RSC. Forms requesting permission to reuse material from The Analyst can be found here: Journals - Permissions form. Papers that are accepted for publication must not be published elsewhere, in whole or in part, except by permission from the Royal Society of Chemistry.
Authors may reproduce/republish portions of their published contribution without seeking permission from the RSC, provided that any such republication is accompanied by an acknowledgement in the form: (Original Citation) - Reproduced by permission of The Royal Society of Chemistry.
Authors submitting work for publication are required to sign an exclusive Copyright Licence which should accompany all submissions (available by request from the Editorial Office or here: RSC Licence to Publish). Publication cannot proceed without a completed Copyright Licence. Submission of a manuscript will be regarded as an undertaking that the same material is not being considered for publication by another journal in any language and will not be considered elsewhere until the RSC informs the author that it does not intend to publish the work.
Authors are responsible for obtaining permission from the appropriate publisher when reproducing figures.
2.5 Advance Articles
The RSC publishes all of its journal articles on the web as soon as they have completed the production process, up to 6 weeks in advance of being published in print. This service is called 'Advance Articles'. These articles are available in full HTML and are assigned a Digital Object Identifier (DOI) to allow the referencing of the articles before the Volume, Issue and Page details of the article are known. Advance Articles for each RSC journal are accessible from the individual journal home pages on the RSC web site. Once an article is assigned to a published issue the electronic versions are accessible from the web contents page of that issue and the article is removed from the Advance Articles area. The DOI and the web address of the article do not change. PDF files of the articles are also made available when the article is assigned to an issue. Further details are available on the Advance Articles homepage
2.6 Digital Object Identifier
Digital Object Identifiers (DOIs) are unique identifiers for articles. The Royal Society of Chemistry prints a DOI on the title page of each article appearing in the print and web edition of The Analyst. DOIs will be used in the near future for identifying and citing articles published online without volume or issue information. Further information about DOIs and their usage can be found at www.doi.org
2.7 Reference Linking
The world's leading scientific, technical, and medical publishers, including RSC, have joined to form the non-profit, independent organization, Publishers International Linking Association, Inc. (PILA), which operates "CrossRef". CrossRef effects linkages through Digital Object Identifiers (DOI), which are tagged to article metadata supplied by the participating publishers. A researcher clicking on a link (the format of which is determined by publisher preference; for example, a CrossRef button, or "Article" in html) will be connected to a page on the publisher's website showing a full bibliographical citation of the article, and, in most cases, the abstract as well. The reader can then access the full text article through the appropriate mechanism; subscribers will generally go straight to the text, while others will receive information on access via subscription, document delivery, or pay-per-view. Further information can be found at www.crossref.org/ |

Manuscripts should be in accordance with the style and usage shown in recent copies of The Analyst. Conciseness of expression is expected: adopting a logical order of presentation, with suitable paragraph or section headings, increases clarity. |
|
3.1 |
Order of presentation |
|
(a) |
Title. This should be brief but informative with an adequate indication of the original features of the work. The title should usually include the analyte being determined or identified, the matrix and the analytical method used. Acronyms and subtitles should be avoided. |
|
(b) |
Authorship. To facilitate abstracting and indexing by Chemical Abstracts Service, and other abstracting organisations, at least one forename should be included with each author's family name. The corresponding author should be indicated with an asterisk and an Email address supplied. |
|
(c) |
Summary/abstract. A summary of about 100 (communications) to 200 words (full papers), describing the purpose of the work and drawing attention to the novel aspects, should be provided for all papers. It should be essentially independent of the main text and include relevant quantitative information such as detection limits, precision and accuracy data. |
|
(d) |
Aim of investigation/introduction. A concise introductory statement of the object of the investigation with any essential historical background, supported by appropriate citation of relevant references (particular attention should be paid to recently published literature). The section should conclude with an unambiguous statement of the novel features of the work. |
|
(e) |
Description of the experimental procedures. Working details must be given concisely. Analytical procedures should be given in the form of instructions and should be succinct; well known operations should not be described in detail. Suppliers of equipment and materials should be mentioned. The choice of any optimisation procedure (in accordance with an accepted protocol) must be justified and any figure of merit clearly stated. This section should also include information on how a new method was validated, including a description of the statistical procedures used. Descriptions of methods should be supported by experimental results showing accuracy, precision and selectivity. |
|
(f) |
Results and discussion. Results are best presented in tabular or diagrammatic form (but not both for the same results), followed by an appropriate statistical evaluation, which should be in accordance with accepted practice. Any discussion should comment on the scope of the method and its validity, followed by a statement of any conclusions drawn from the work. Appropriate negative results should also be reported. A separate conclusions section is not encouraged but, if included, it should not simply duplicate statements in the discussion. |
|
(g) |
Acknowledgements. Contributors other than co-authors, companies or sponsors may be acknowledged in a separate paragraph at the end of the paper. Titles may be given but not degrees. |
|
(h) |
References. References should be numbered serially in the text by means of superscript figures, e.g., Foote and Delves,1 Burns et al.2 or . . . in a recent paper3 . . ., and collected in numerical order under the heading 'References' on a separate page at the end of the paper. Journal titles should be abbreviated according to the Chemical Abstracts Service Source Index (CASSI) and all the authors' names and initials should be given. Articles "in the press" should be listed only if formally accepted for publication. Otherwise "submitted to" or "unpublished work" should be used. Where possible, page ranges should be stated.

Internet Sources. Internet sources should include the author (if any), the title of the site, the URL (address), and the date accessed
Authors must, in their own interest, check the lists of references against the original papers; second-hand references are a frequent source of error. References to conference abstracts which have not been published in the open literature are not acceptable. The number of references must be kept to a minimum. |
| 3.2 |
Figures and tables
Table column headings should be brief. Tables consisting of only two columns can often be arranged horizontally. Tables must be supplied with titles and be so set out as to be understandable without reference to the text.
Either tables or graphs may be used but not both for the same set of results, unless important additional information is given by so doing. The information given by a straight-line calibration graph can usually be conveyed adequately as an equation or statement in the text.
Column headings and graph axis labels should be in accord with SI conventions. Thus, the expression of numerical values of a physical quantity should be dimensionless, i.e., the quotient of the symbol for the physical quantity and the symbol for the unit used, e.g., c/mol dm-3, or some mathematical function of a number, e.g., ln(c/mol dm-3). Further examples are  /cm-1,  /cm, mass of substance/g and flow rate/ ml min-1. For units which are already dimensionless, i.e., ratios such as % or ppm, the type of ratio is indicated in parentheses, e.g., c (%) or c (ppm). The diagonal line (solidus) will not be used to represent 'per'. Units such as grams per millilitre should be expressed in the form g ml-1. It should be noted that the 'combined' unit, g ml-1, must not have any 'intrusive' numbers. To express concentration in grams per 100 millilitres, the word 'per' will still be required: concentration/g per 100 ml. It may be preferable for an author to express concentrations in grams per litre (g l-1) rather than grams per 100 ml.
Best quality original diagrams should be supplied. Figure captions should be supplied separately to the figures. Figures which have been computer generated should be saved in formats TIFF or EPS at a minimum of 600 dpi and submitted in a separate file to the text.
In the majority of cases, author's figures will be reduced in size so that they are less than 20 picas (83 mm) in width and will fit into a single column in the journal. Authors must consider if originals (in particular text on figures and axes labels) will remain legible if reduced to conform to this column width. Where possible, illustrations should be provided in the size they are to appear when published. Authors are discouraged from supplying full page, outsized diagrams and graphs. The intention is to avoid any loss of detail that can occur when oversized originals are reduced in size before printing. It is recognized that this may be impossible where illustrations are produced manually (hand drawn). In this event artwork should be submitted at twice the size of the final printed version. All lettering appearing on figures should be in a clear font (sans-serif is preferable) and should be 6-8 point type (on reduction where necessary). Lines should be of sufficient thickness and symbols of sufficient size to reproduce well even when the illustrations are reduced in size. The optimum line thickness when printed is 1 pt. Symbols should be approximately 1 mm in diameter when printed. The use of shading and tints should be avoided as these are unlikely to reproduce successfully.
Figures and tables should be kept to a minimum; a maximum of 5 figures and/or 5 tables is recommended. Authors should consider using the free ESI service for depositing extensive sets of tabulated data. |
| 3.3 |
Photographs and use of colour
Photographs can be submitted if they convey essential information that cannot be shown in any other way. They should be submitted as glossy or matt prints made to give the maximum detail. Colour figure reproduction in printed journals is normally provided free of charge if there is a scientifically compelling case for the use of colour. The provision of free colour reproduction is determined by consideration of whether or not the scientific information can be assimilated without the use of colour. If there is no scientifically compelling case for the use of colour, but the author prefers colour, then the author will be charged ?50/page (+VAT), this being a partial contribution to the additional production costs. Alternatively, authors may wish to consider using the free ESI service for presenting colour figures. Details about the RSC policy on printing colour can be found here: Statement on provision of colour |
| 3.4 |
Electronic supplementary information
Electronic supplementary information (ESI) is a free facility that enables authors to enhance and increase the impact of their articles. Such data can take full advantage of the electronic medium, allowing use of full colour diagrams, 3D molecular models, movie clip files etc. Authors can also improve the readability of their articles by placing appropriate material, such as repetitive experimental details and extensive supporting data, with the ESI service. All information in the ESI service is fully archived and is totally free to all readers. ESI should be made available with a manuscript for refereeing. Authors wishing to submit ESI for an article should, where possible, supply data in the following file types: GIF, JPEG, figures embedded in a Microsoft Word file (for graphical files); plain text files - txt, Microsoft Word - doc, WordPerfect - wpd (for text); CIF (for crystallographic data); Brookhaven PDB, XMOL XYZ, MDL MOL, MDLSketch, RASMolScript, CSML (for 3D molecular information files); MOPACInput, GaussianInput, VRML (for 3D images); JCAMP-DX - jdx (for, e.g., spectra); MPEG, Quicktime (for movie clips). For more details and a "tutorial" on how to prepare and view electronic supplementary information visit the ESI homepage |
| 3.5 |
Nomenclature
Current internationally recognized (IUPAC) chemical nomenclature should be used. Common trivial names may be used, but should first be defined in terms of IUPAC nomenclature. Further details are listed in the following: IUPAC Publications on Nomenclature and Symbolism |
| 3.6 |
Symbols and units
The SI system of units, as recommended by IUPAC, should be followed. Their basis is the 'Systeme Internationale d'Unites' (SI). A detailed treatment is given in the 'Green Book': Quantities, Units and Symbols in Physical Chemistry (Blackwell, Oxford, 1988 edn.). When non-SI units are used they must be adequately explained unless their definition is obvious (e.g., °C and ?. The derivation of derived non-SI units should be indicated. |
| 3.7 |
Abbreviations
Abbreviational full stops are omitted after the common contractions of metric units (e.g., ml, g, mg, mm) and other units represented by symbols. Abbreviations other than those of recognized units should be avoided in the text except after definition. Upper case letters without points should be used for abbreviations for techniques and associated terms subsequent to definition e.g., HPLC, AAS, XRF, UV, NMR. The abbreviations Me, Et, Prn, Bun, Bui, But, Bus, Ph, Ac, Alk, Ar and Hal can be used; others should be defined. Substituents should be indicated by R (one) or by R? R? R?(more than one).
Percentage concentrations of solutions should be stated in internationally recognized terms. Thus the symbols 'm' instead of 'w ' for mass and 'v' for volume are to be used. The following show the manner of expressing these percentages together with an acceptable alternative given in parentheses: % m/m (g per 100 g); % m/v (g per 100 ml); % v/v. Further implications of the use of the term 'mass' are that 'relative atomic mass' of an element (Ar) replaces atomic weight, and 'relative molecular mass' of a substance (Mr) replaces molecular weight.
Concentrations of solutions of the common acids are often conveniently given as dilutions of the concentrated acids, such as 'dilute hydrochloric (1 + 4)', which signifies 1 volume of the concentrated acid mixed with 4 volumes of water. This avoids the ambiguity of 1:4, which might represent either 1 + 4 or 1 + 3. Dilutions of other solutions should be expressed in a similar manner. Molarity is generally expressed as a decimal fraction (e.g.., 0.375 mol dm?). |
