New considerations in detector-application relationships.
This report relates new ways of using refractometer and ultraviolet (UV) detectors in liquid chromatography (LC) which involve less sample preparation and handling. A new cell design is proposed which extends the sensitivity of UV detectors by correcting for refractive index effects as light passes through a cell. Finally, a technique called "trace enrichment" is proposed for concentrating non-polar organics, in very low concentration, from polar sources (river water) for analysis by LC.
