Guidelines for Authors
The Brazilian Journal of Analytical Chemistry (BrJAC) is dedicated to the diffusion of significant and original knowledge in all branches of Analytical Chemistry. BrJAC is addressed to professionals involved in science, technology and innovation projects in Analytical Chemistry, at universities, research centers and in industry.
Manuscripts submitted for publication in BrJAC cannot have been previously published or be currently submitted for publication in another journal. BrJAC publishes original, unpublished scientific articles and technical notes that are peer reviewed in the double-blind way.
BrJAC’s review process begins with an initial screening of the manuscripts by the editor-in-chief, who evaluates the adequacy of the study to the journal scope, and an analysis of similarities. Manuscripts accepted in this screening are then forwarded to at least two reviewers who are experts in the related field. A larger number of reviewers may be used at the discretion of the Editor. As evaluation criteria, the reviewers employ originality, scientific quality, contribution to knowledge in the field of Analytical Chemistry, the theoretical foundation and bibliography, the presentation of relevant and consistent results, compliance to the BrJAC’s guidelines, clarity of writing and presentation, and use of grammatically correct English.
Note: In case the Editors and Reviewers consider that the manuscript requires an English revision, the authors will be required to send an English proofreading certificate, by the ProofReading Service or equivalent service, before the final approval of the manuscript by BrJAC.
BrJAC offers multiple contents
BrJAC is a quarterly journal that, in addition to scientific articles and technical notes, also publishes reviews, interviews, points of view, letters, sponsor reports, and features related to analytical chemistry.
Brief description of the documents that can be submitted by the authors
- Articles: Full descriptions of an original research finding in Analytical Chemistry. Articles undergo double-blind full peer review.
- Reviews: Articles on well-established subjects, including a critical analysis of the bibliographic references and conclusions. Manuscripts submitted for publication as Reviews must be original and unpublished. Reviews undergo double-blind full peer review.
- Technical Notes: Concise descriptions of a development in analytical method, new technique,procedure or equipment falling within the scope of BrJAC. Technical notes also undergo double-blind full peer review.
- Letters: Discussions, comments, suggestions on issues related to Analytical Chemistry, and consultations to authors. Letters are welcome and will be published at the discretion of the BrJAC editor-in-chief.
BrJAC uses the online Manuscript Manager System for the submission of manuscripts. This system guides authors stepwise through all the submission process. The texts must be uploaded in Word files, which will be converted to a single PDF file used in the double-blind peer review process. All correspondence, including notification of the Editor’s decision and requests for revision, is sent by e-mail. Please submit your manuscript at www.manuscriptmanager.net/brjac
The mandatory files to be uploaded are: Cover letter, Manuscript and Title Page (double-blind review).
Templates for these files are available at the end of this page.
- Language: English is the language adopted by BrJAC. The correct use of English is of utmost importance. In case the Editors and Reviewers consider that the manuscript requires an English revision, the authors will be required to send an English proofreading certificate before the final approval of the manuscript by BrJAC.
- Required items: the manuscript must include a title, an abstract, keywords, and the following sections: Introduction, Materials and Methods, Results and Discussion, Conclusion, and References.
- Identification of authors: the manuscript file must NOT contain the authors’ names nor affiliations. This information must be in the Title Page. This rule is necessary because the manuscript is subjected to double-blind review.
- Layout: the lines in the manuscript must be numbered consecutively and double-spaced.
- Graphics and Tables: must appear close to the discussion about them in the manuscript. For figures use Arabic numbers, and for tables use Roman numbers.
- Permission to use content already published: for figures, graphs, diagrams, tables, etc. identical to others previously published in the literature, the author must ask for publication permission from the company or scientific society holding the copyrights, and send this permission to the BrJAC editor-in- chief with the final version of the manuscript.
- Chemical nomenclature: should conform to the rules of the International Union of Pure and Applied Chemistry (IUPAC) and Chemical Abstracts Service. It is recommended that, whenever possible, authors follow the International System of Units, the International Vocabulary of Metrology (VIM) and the NIST General Table of Units of Measurement. Abbreviations are not recommended except those recognized by the International Bureau of Weights and Measures or those recorded and established in scientific publications.
- References: must be cited by numbers in square brackets. It is recommended that references older than 5 (five) years be avoided, except in relevant cases. Include references that are accessible to readers. References should be thoroughly checked for errors by the authors before submission. See how to format the references in the following item.
