Final Considerations


The BrJAC is dedicated to the diffusion of significant and original knowledge in all branches of Analytical Chemistry and Bioanalytics, and it is addressed to professionals involved in science, technology and innovation projects at universities, research centers and in industry.


In addition to publishing scientific articles, reviews and technical notes, the goal of the BrJAC is also to discuss trends and needs in Analytical Chemistry through opinion editorials, points of view, letters, and interviews with renowned senior investigators.

Brief history of the BrJAC

The BrJAC is the first Brazilian scientific journal dedicated to all branches of Analytical Chemistry. It was launched on June 18, 2010 to fulfill an idealistic purpose of a group of researchers to achieve actual academic-industrial integration towards innovation and technical-scientific development. The composition of the BrJAC Editorial Board, which brings together professionals of the Analytical Chemistry field who work in academia, private companies and public institutions, reflects the search for academic-industrial integration. Since 2010, the BrJAC has presented an upward trend in scientific quality and worldwide visibility.
In 2019, the BrJAC created the "Young Talent in Analytical Chemistry Award" to recognize young outstanding researchers in Analytical Chemistry and Bioanalytics. The choice of the researcher to be awarded was made by a committee designated by the Editor-in-Chief of the BrJAC.
This award will be offered annually at events held in Brazil and related to analytical chemistry, such as the National Meeting of Analytical Chemistry (ENQA) and the Analitica Latin America Congress, which take place in alternate years. The award consists of a merit recognition diploma and a registration voucher for the national event subsequent to the award.

Ethics and Integrity Politics

The BrJAC adopts good practices, integrity and ethical conduct in the publication of original and unpublished scientific articles, reviews and technical notes. Based on the Core Practices of the Committee on Publication Ethics (COPE), the BrJAC strives to combat misconducts such as: unethical research, manipulation, fabrication, the omission of data, falsification, including image manipulation, plagiarism, selective reporting, redundant publication, inappropriate authorship, gift and ghost authorship, publications without consent, the omission of authors, and undeclared conflicts of interest. All manuscripts submitted to the BrJAC undergo similarity analysis using the iThenticate software.
The BrJAC discourages and restricts the practice of excessive self-citation by the authors.
The BrJAC does not practice coercive citation, that is, it does not require authors to include references from BrJAC as a condition for achieving acceptance, purely to increase the number of citations to articles from BrJAC without any scientific justification.
Misconduct will be treated according to the COPE's recommendations ( and the Council of Science Editors White Paper on Promoting Integrity in Scientific Journal Publications (
Whenever necessary, the BrJAC will publish erratum, amendments, clarifications, expressions of concern, retractions and apologies, in accordance with the COPE Code of Conduct.

Conflicts of Interest

Conflicts of interest include financial and nonfinancial relationships (e.g., personal relationships) that may affect the exempt evaluation of a manuscript.
The corresponding author must declare in the Cover Letter and on behalf of all of the authors of the manuscript any financial conflicts of interest or lack thereof. This statement should include all potential sources of bias such as affiliations, funding sources and financial, management or personal relationships which may constitute a conflict of interest.
With regard to reviewers, the invited reviewers must alert the editor about any potential conflict of interest with the study to be evaluated and decline to review the manuscript when a possibility of a conflict exists.


When submitting their manuscript for publication, the authors agree that the copyright will become the property of the Brazilian Journal of Analytical Chemistry, if and when accepted for publication. The submitting author declares in the Cover Letter, on behalf of all other co-authors, to consent to this transfer.
The copyright comprises exclusive rights of reproduction and distribution of the articles, including reprints, photographic reproductions, microfilms or any other reproductions similar in nature, including translations.

Reproduction of Already Published Material

When a manuscript submitted to the BrJAC contains any proprietary text, figure, scheme, illustration, photo, table or other material already published in another paper or book, the authors must obtain copyright permission from the publisher of the original document, even if these materials have been published by the same authors. Such specific Copyright Permissions must be included among the uploaded documents in the manuscript management system at the time of submission.
Researchers who want to reuse any document or part of a document published in the BrJAC should request reuse permission from the BrJAC Editor-in-Chief, even if they are the authors of such document. A template for requesting reuse permission can be downloaded here.

Article Processing Charge

The BrJAC does not charge authors an article processing fee.


The BrJAC does not consider submissions of manuscripts that have been posted to preprint servers prior to submission, and will withdraw from consideration any papers posted to those servers prior to publication.

Manuscript Submission

The submission of manuscripts is done online by a submitting author through a digital manuscript manager system. Manuscripts must be prepared according to the BrJAC Guidelines for Authors, which is accessible from the menu at the top of this website. Manuscripts in disagreement with the BrJAC guidelines are not accepted for revision.
The submitting author is responsible for including all co-authors in the Authors section of the manuscript manager system and for the integrity of the submitted documents. It is the duty of the submitting author to inform their collaborators about the manuscript content and obtain their permission for submission and eventual publication. After submission, all co-authors will receive an automatic alert and will have the opportunity to confirm whether or not they are co-authors.
All correspondence regarding the submission progress will be sent through the manuscript management system to the submitting author who is responsible for reporting to the co-authors on the progress, revision, acceptance or rejection, and approval of the proofs prior to publication.
The co-authors can follow the manuscript submission progress at any time by accessing the manuscript manager system website.

Manuscript Peer Review System

The BrJAC adopts peer review in double-blind mode, and the manuscripts are evaluated by at least two reviewers. A third evaluation may occur at the discretion of the editor. Eventually, the editor, in addition to the reviewers, may also request corrections from the authors.
The main criteria for manuscript evaluation are originality, scientific quality and contribution to knowledge in the field of Analytical Chemistry, theoretical foundation and bibliography, the presentation of relevant and consistent results, clarity and grammatical correction in the writing of the text and compliance with the BrJAC guidelines for authors.
The 1st-round review process usually takes around 5-6 weeks. If the manuscript is not rejected, but needs corrections, the authors will have one month to submit a corrected version of the manuscript. In another 3-4 weeks, a new decision on the manuscript may be presented to the corresponding author.
The manuscripts accepted for publication are forwarded to the article layout department. Minor changes to the manuscripts may be made, when necessary, to adapt them to BrJAC guidelines or to make them clearer in style, respecting the original content. The articles are sent to the authors for approval before publication. Once published online, a DOI number is assigned to the article.
