Analytical Chemistry by American Chemical SocietyAnalytical Chemistry is a peer-reviewed research journal that is devoted to the dissemination of new and original knowledge in all branches of analytical chemistry. Fundamental Articles, Letters to Analytical Chemistry, and Technical Notes may address the general principles of chemical measurement science and need not directly address existing or potential analytical methodology. Manuscripts may be entirely theoretical with regard to analysis, or they may report experimental results that bear on theory. They may contribute to any phase of analytical measurements and concepts thereof, including but not limited to: sampling, bioanalysis, electrochemistry, mass spectrometry, microscale and nanoscale systems and structures, environmental analysis, separations, spectroscopy, chemical reactions and selectivity, instrumentation, imaging, surface analysis, and data processing. In addition, the journal publishes Features and news articles about major advances, trends, and challenges in analytical chemistry. These articles include peer-reviewed Features written by researchers and news stories that discuss novel analytical concepts and instruments. Both the Features and news stories draw upon scientific literature published in a wide range of related journals.
