Flow-injection systems for sample introduction in mass spectrometry

A feasibility study of flow injection/mass spectrometry is described. Flow-injection systems can be used either for direct introduction of an analyte to the mass spectrometer, or to convert the analyte to a suitable form for detection. This ability, along with the members separation, provides enhanced selectivity and scope. The selectivity and sensitivity inherent in mass spectrometry serve to increase the utility of flow-injection methods. Determination of arsenic and chloroform are discussed.
