|Analytical chemistry is the branch of science that provides knowledge of compound separation, identification and quantification that can be useful for measuring bioavailability of drugs, purifying drugs during synthesis, and identifying drug metabolic pathways. To accurately quantify drugs and metabolites in pharmacokinetic, transport, and delivery studies, a strong understanding of analytical chemistry principles is necessary and only well-characterized analytical methods should be used to ensure the integrity of collected data. Chemical Sciences journal is the best Peer- reviewed journals in Analytical Chemistry. The journal follows robust and stringent peer review process for processing and publication of articles. Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals. OMICS Group publishes original scientific and specialized articles on all aspects of Chemistry, and related scientific disciplines. Also provides the researchers and students descriptions of new experimental methods of chemicals, or new interpretations of existing result.
