He/She/They must reveal their direct or perceived connection and/or conflict of interest to AOAC staff and the ERP. It is acceptable to recuse oneself and abstain from voting. ERP members of the same affiliation have only one (1) vote counted. Serves as a resource. Members of the Committees on Safety and Statistics also serve as a resource to both the ERP and method authors. Method authors will be invited to recommend three (3) ERP members to conduct peer review of the manuscript.

More than one ERP member may have the same affiliation

Official Methods Board will assign a member to be a liaison to the ERP ERP members may participate in the peer review process of the manuscript publication

I. General Guidelines Below is the general format of manuscripts with Official Methods or candidate Official Methods for ERP review and AOAC Publications.

A. Before the Method

o Title of the Manuscript o Author names and Affiliations o Abstract o Introduction o Summary of Validation Study Design or Protocol used. B. Method (See section II for the Formatting of Methods in Manuscripts)

C. After the method o Manuscripts should include the following sections: Results and Discussion, Conclusions, Acknowledgments, and References. II. Format and Style for Official Methods The Method portion of the manuscript should be included after the Introduction. Methods must include the following elements: Title of the Method The title should include the Method number, analyte, matrix, technology used and the official status. AOAC will provide the Official Method number after the paper is received for publication as such, authors should use the following 2020.xx


AOAC Official Method 2020.xx Analyte in Matrix Technology used First Action 2020 (use the year that the method was approved)

Applicability statements Applicability statements should include the list of matrix(es) along with specific matrix types and range or limits of determination or detection. Applicability statements should address utility and limitations on use of method or other information. [Applicable for determination of ….] Caution Statements List any statements of caution after the applicability section. Review all methods for potential hazards. Authors should automatically incorporate safety statements. Decisions regarding inclusion of caution statements should be practical; overuse will be self ‐ defeating. Methods that create toxic, obnoxious or environmentally hazardous fumes and wastes should contain practical directions for disposal. Specify precautions and possible hazards in carrying out method, including safety information on equipment, techniques and practices, and safe handling of chemicals, acids, alkalies, microorganisms, and solvents. Example: Caution: Refer to the material safety data sheets for all chemicals prior to use. Use all appropriate personal protective equipment and follow good laboratory practices. Performance Parameters Include statistical data if the study provides sufficient information with regard to the reliability of the method. All headings should be set in Alphabetical Order i.e., A. Principle, B. Apparatus, C. Reagents. Methods should be laid out in the following order: A. Principle

Explains scientific premise on which the method is operates specifically the mechanism of the analysis. Explain the purpose of various steps or the basis of unfamiliar or unusual reactions. Include the scope and sensitivity of the method—its applicability to certain types of samples and its non ‐ applicability, because of interference, solubility, or other reasons, to other types of samples. Methods are divided into several descriptive sections i.e., Apparatus, Reagents, Reagent Preparation, Standard Preparation, Sample Preparation, Extraction . The sections should include specifications for necessary laboratory apparatus and reagent preparations. See also Definition of Terms and Explanatory Notes . NOTE: Official Methods will need to include InChi numbers and CAS numbers where appropriate. B. Apparatus Lists the equipment that requires assembly or that has specifications critical to the method performance. Describe equipment in terms of performance characteristics. List the necessary laboratory apparatus. For more information see “ Definition of Terms and Explanatory Notes ” Apparatus should be set as in the following example: (a) Ultra ‐ HPLC (UHPLC) system —Nexera (Shimadzu, Kyoto, Japan) or equivalent LC system consisting of a dual pump system, a sample injector unit, a degasser unit, and a column oven. (b) Triple ‐ quadrupole mass spectrometer —Triple Quad 6500 (Sciex, Framingham, MA) or equivalent tandem MS (MS/MS) instrument. (c) Column —Kinetex C18 core ‐ shell, 2.6 μ m, 2.1 × 50 mm (Phenomenex, Torrance, CA) or equivalent. C. Reagents Do not list common reagents which would ordinarily be expected to be available in a well ‐ equipped analytical laboratory. Reagents without specifications are automatically reagent grade, conforming to the specifications of the American Chemical Society (ACS) when such specifications exist. Reagents should follow the same format as in the above example under Apparatus. D. Reagent Preparation, Standard Preparation, Sample Preparation, Extraction Sections Use these sections for materials requiring directions for preparation, purification, or standardization. Standard compounds will often need specifications or a source of supply. The sections should use the same style and format as in the above example under Apparatus. E. Determination If a method is fairly straight forward or consists only of a single major step, describe all operations under this heading. If the method is complex, however, divide the determinative section into several parts which may be characterized by the type of operation performed. Be sure to identify all critical control points. F. Calculations Include calculations in a method for convenience to avoid the need for looking up factors and deriving equations, particularly when a series of multiple dilutions or aliquots are used at various steps in the method. Take particular care to ensure that there is no ambiguity with regard to the entries in the numerator and the denominator. G. Data Handling A section on data handling should be included if necessary. Example : Report results as μ g/hg to one decimal place or as IU/hg to zero decimal places. Other sections may be included as needed and should be labelled in alphabetical order (i.e., H. Chromatography) Tables and Figures Tables and Figures should be in separate documents and clearly labelled. Do not intersperse tables and figures within the text document. Tables and figures should be numbered consecutively as Table 1, Table 2, Figure 1, Figure 2. For instructions on how to layout Tables and Figures specifications please visit our Instructions to Authors page. Supplemental information Supplemental information is allowed and should be included as a separate Word document clearly labelled. Supplemental information should be cited in the text. Supplemental data may include large tables, figures or appendices. Please note: this information will be available on the online Journal site and will be uploaded as submitted. It will not be copyedited or typeset.

Detailed Author Instructions for Each Section of Manuscript Including Tables and Figures Please follow these instructions closely; doing so will save time and revision. Note: if the instructions are not followed and the paper is accepted the Editorial Office will return the paper to the author and the instructions will need to be followed before production and publication can begin. If the Section Editor sends notification to author that changes are necessary, it is the author’s responsibility to upload updated files per Section Editor’s comments before approval is granted. 1. Write in clear, grammatical English. 2. Double space all materials. Do not right justify or use proportional spacing; avoid hyphenation. 3. Suggest at least three qualified reviewers (i.e., Expert Review Panel members). Text Please send manuscript text as a Word file. Tables and figures should set as separate files clearly named (i.e., table 1, table 2, figure 1, figure 2 etc.). DO NOT intersperse tables and figures in text. Choose a title that is as descriptive of the paper’s content as possible. Do not try to make the title clever or “catchy.” Use specific terms that will serve as index entries; information services increasingly rely on titles for indexing. Avoid the use in the title of symbols, formulas, and terms that must be defined. Contact AOAC staff in Standards and Official Methods SM or in Publications for style suggestions for method manuscripts if needed. 2. Author information Give the full first name, middle initial, and surname of each author. Do not include academic titles. List the affiliation(s) of the author(s) in a form that will serve as a complete mailing address, including zip code. The corresponding author needs to be identified and e ‐ mail address supplied. Use the affiliation at which the work was performed; if authors have moved to a different affiliation or if any of the authors have moved to a different address, give the address in a footnote, indicated by a superscript Arabic numeral. It is generally assumed that all persons listed as co ‐ authors of a paper or report have made substantial contributions to the work reported. Other supplemental information should be moved to Acknowledgements i.e., supported by a grant or contract, taken from a thesis or dissertation, publication authorized by an institution, or part of the institution’s publication series. 3. Abstract 250 words. Provide specific information, not generalized statements; abstracts must be organized and include the following subheads: Background, Objective, Methods, Results, Conclusions, Highlights. 4. Introduction Include a statement of the purpose of the work, together with enough background to enable the reader to attain the proper understanding and perspective. State the use of the compound being discussed. Cite the work of others which contributed directly to the present paper but do not attempt to survey the entire literature of the field unless the paper is intended to be a review. Consider the following hypothetical questions in deciding what information to include in the introduction: Why was the work done? Why was a method needed? Did any methods exist previously, and if so, why were they not suitable? If a new method had to be developed, upon what established chemical, biological, or physical principles was it based? What general approach was used? Format and Style 1. Title

If an interlaboratory study is being reported and a background report has already been published, do not repeat all the introductory material; instead, cite the earlier report and go directly to the description of the interlaboratory study. 5. Study Design Include the type of study(ies) that were conducted including, Collaborative Study, Single Laboratory Validation, etc. Include a section sub ‐ heading for each type of study used to develop data in the validation of the method written in the paper with a brief description of the study, and samples used. Do not include the results, just a summary of what was done to evaluate the method and collect the data. Include any notable procedures in the study design. 6. Method Consult section II (Format and Style for Official Methods of Analysis) and section D of this Guide on preparing methods. Follow these general principles: Write the method in imperative style (“add 10 mL”; evaporate the solution to dryness,” instead of “10 mL was added;” “the solution was evaporated to dryness”). Place important reagents and apparatus in separate sections (or combine them into one separate section) before the actual determination; indicate specifications, source of supply, and instructions for preparation of working solutions where pertinent. List, each reagent or piece of apparatus as a separate item. Provide enough detail so that the reader can repeat the method if he wishes, and indicate how the results are to be calculated, if a calculation is required. 7. Results/Discussion Discuss the results fully enough so that their significance is evident, and conclusions can be drawn from them, but do not use the Discussion merely to repeat data that are given in tables and figures. Provide a statistical treatment of the data if an interlaboratory study has been conducted and where appropriate in other reports and papers. Indicate whether certain data have been rejected and name the statistical test which was the basis for rejection. Try to provide an explanation for unexpected results if possible or, if you cannot explain them, state this fact. In general, do not present the same quantitative data in both a table and a figure in the same paper, because this is expensive and a waste of journal space and money; choose one form or the other. (The exception to this rule is Youden’s diagrams.) Although it is difficult to generalize consider using figures where trends or relationships are especially important and using tables where individual results should be reported, e.g., interlaboratory studies. If a method is being studied, give both recovery data obtained on known samples (usually prepared by the author) and results on unknown samples of the type encountered in regulatory work. Except in unusual cases, do not include straight ‐ line graphs; instead, state in the text the curve is linear in the range of interest. Cite tables and figures consecutively in text with Arabic numerals. 8. Acknowledgments Give brief thanks (no social or academic titles). Financial aid should be acknowledged in this section. 9. References Submitted papers or unpublished oral presentations may not be listed as references; cite them in text as unpublished data or personal communications. Cite all references to previously published papers or papers in press in numerical order in text with number in parentheses on ‐ line (not superscript). List references numerically in References in exactly (arrangement, punctuation, capitalization, use of ampersand, etc.) the same styles of examples shown below or see recent issue of the Journal for less often used types of entries. Follow Chemical Abstracts for abbreviations of journal titles.

10. Tables and Figures Tables

Tables should be supplied in an editable format (e.g., Microsoft Word), not as an image file. Avoid excessive formatting and the use of tabbed spacing to indicate alignment and ensure that any formatting or superscript symbols such as asterisks are explained in the table footnote. Unless the journal’s house style indicates otherwise, provide units in column or row headers, rather than in the table body. Consider the size and layout of the printed journal (or online PDF) when deciding on the dimensions of your table. All tables provided should be cited within the article text. Figures Each figure should be submitted as its own file. Supply figures at the intended print size. Resolution at this size should be no less than 300dpi for halftone images, 600dpi for composite images, and 1200 dpi for line art, and at no less than 1080px width. For typical print page sizes please visit . The dimensions of the printed journal or online PDF should also be considered when choosing figure layout, to minimize white space when reproduced at the intended size. Most standard figure formats are acceptable, but .tiff is recommended for halftone and composite images, .eps for line art and vector graphics. Images embedded into Microsoft Word are often not good quality. Images created with multiple layers should be flattened to a single layer prior to submission. Multi ‐ paneled figures should be supplied as a single file with each panel lettered clearly, according to journal style. Avoid placing letters over shaded areas if possible. Miscellaneous Abbreviation for liter is L; abbreviation for micron is μ . Do not italicize common Latin expressions such as et al. and in vitro; for nomenclature of spectrometry, gas chromatography, and liquid chromatography, follow practice of American Society for Testing and Materials. Do not use numbering in your headings or subheadings. Major headings should be set in bold font, secondary

headings in italic font, and third level headings should be set using alphabetical lists (a) . The Journal prefers the use of the front solidus (/) do not use superscript ‐ 1 (i.e., μ g/kg).

Footnotes Avoid use of footnotes to text.

Special Instructions for Journal Articles containing Official Methods of Analysis First and Final Action Methods First and Final Action Official Methods will need to include InChi numbers and CAS numbers where appropriate.

STAGE 1: Project Initiation: Agreement and alignment on goals and scope of work for the type of standard to be developed and key experts, leading authorities, and stakeholder organizations that should be involved. Outreach and engagement about upcoming standards development activities. This stage includes assessing interested stakeholders and working group members for balance of interests. An OMB liaison is also assigned at this stage. This stage encompasses Detailed Steps 1 and 2. STAGE 2: Working Group Draft Standard: Working group onboarding, launching, and developing draft standard that can be posted for public comment and additional stakeholder input via working group consensus. Working groups meet as often as needed to achieve consensus with allowance for working group members to express objections and appeals and have those views considered before the WGDS is ready for posting for public comment. This stage includes the public comment period. This stage encompasses Detailed Steps 3 and 4. STAGE 3: Reconcile comments and Revision of Working Group Draft Standard: Working group review and reconciliation of written and oral comments received. The WGDS is revised as needed based on the reconciliation of the comments and input. The working group shall review draft with allowances for working group members to express objections and appeals and have those views considered before reaching consensus on the document. Working group consensus makes the revised draft a Working group Draft Standard – Revision 1. This stage includes preparing the WGDS ‐ R1 for presentation to a stakeholder assembly for consensus. This stage encompasses Detailed Step 5. STAGE 4: Stakeholder Assembly Consensus Draft Standard (SACDS): WGDS ‐ R1 is presented to the stakeholders with public comments reconciliation. Stakeholders deliberate on acceptability of the draft standard and may include any tweaks/clarifications that might be needed to the draft standard. Stakeholders may reach consensus to accept a final version of the document, an SACDS, or make recommendations to revise the draft. This stage encompasses Detailed Step 6. STAGE 5: Due Process Audit Review: OMB to review the outcomes of the stakeholder assembly consensus. If the draft standard is a consensus draft standard, then the OMB needs to evaluate the process for how the standard was developed and ensure that due process elements were met. OMB will reach consensus on the draft once all questions have been satisfactorily addressed. If approved, the standard is an approved AOAC standard. If the draft standard did not receive consensus by stakeholders, then OMB reviews the recommendations of stakeholders along with the audit. Staff will reconcile any gaps. This stage encompasses Detailed Step 7. STAGE 6: Publication of Standard and Outcomes: Outcomes of all deliberations along with status changes of standards are published in the AOAC Inside Laboratory Management (ILM). Any approved AOAC standards are published in the Official Methods of Analysis of AOAC INTERNATIONAL in both online and subsequent print editions. Press releases may be sent to announce the approval and/or publication of an approved AOAC standard. This stage encompasses Detailed Step 8.

AOAC DUE PROCESS FOR DEVELOPMENT OF NON ‐ METHOD CONSENSUS STANDARDS AND DOCUMENTS Policy for Due Process in the Development of AOAC Standards and Consensus Documents

AOAC INTERNATIONAL (AOAC) develops and publishes voluntary consensus standards and documents in support of method development, method modification, and method use or implementation. AOAC establishes voluntary consensus standards and documents in accordance to national and international principles for ensuring due process. AOAC’s consensus and standards development activities include participation from diverse perspectives across a given analytical industry or community area, discipline or issue. Standards are developed upon consensus of stakeholders. Approval of standards is based upon confirmation that the standard has been developed in accordance with AOAC’s processes 1 and principles, and as outline in Figure 1. Examples of AOAC consensus documents and standards include voluntary consensus standards; performance standards; methods of analysis; guidance documents; concepts of operation; best practice recommendation documents, and sampling approaches. POLICY STATEMENT AOAC develops national and international analytical non ‐ method consensus and standards documents according to the national and international principles for ensuring due process in the development of consensus documents and standards: openness, transparency, lack of dominance, balance, due consideration, coordination, consensus, and appeals. The AOAC Official Methods Board oversees the implementation of scientific and technical policies and procedures established by the AOAC Board of Directors including those for ensuring due process in establishing standards and consensus documents as outlined in Figure 1. The rules of engagement and parliamentary procedures for AOAC standards developing bodies follow Robert’s Rules of Order (latest edition) in accordance with AOAC bylaws and policies.

Figure 1 ‐ Overview Flow for Consensus & Standard Development

1 AOAC has documentation on the details of the processes used to develop its standards and consensus documents. These supporting documentation include terminology, process details in text with an accompanying flowchart, and a document stage handout.

Approved by AOAC Board of Directors on June 10, 2020.
