The articles in TrAC are concise, critical overviews of new developments in analytical chemistry, which are aimed at helping analytical chemists and other users of analytical techniques. These critical reviews comprise excellent, up-to-date, timely coverage of topics of interest in analytical chemistry, such as: analytical instrumentation, biomedical analysis, biomolecular analysis, biosensors, chemical analysis, chemometrics, clinical chemistry, drug discovery, environmental analysis and monitoring, food analysis, forensic science, laboratory automation, materials science, metabolomics, pesticide-residue analysis, pharmaceutical analysis, proteomics, surface science, and water analysis and monitoring.General issues contain critical review articles. Special Issues provide comprehensive updates with critical review articles on particularly topical fields of interest in analytical chemistry.Please note that most articles published in the journal are by invitation of one of the Editors. If you wish to submit a review to TrAC and have not been invited by one of the Editors, please first submit a short proposal using the standard review proposal template directly to the Elsevier EVISE System.Please indicate which of the listed Contributing Editor(s) of TrAC you feel is best suited to review your proposal (please list a maximum of 3 in order of preference).
