Sample/analyte screening systems and chromatography

The paper establishes a distinction between "screening" and "analysis", as well as between "analyte screening" and "sample screening" in the context o f analytical sciences. The paper then deals with the main relationships bet ween screening and chromatography: analyte screening using chromatographic techniques, sample screening before the implementation of chromatographic a nd electrophoretic separation and the use of such techniques to confirm and expand the binary information provided by sample screening systems.
