Abstract

Multiple detection systems are reviewed as an approach to improve selectivity, increase the number of compounds detected, aid in confirming identity, and reduce the time of analysis. Various configurations of separators, detectors, and operating parameters are outlined. The advantages, disadvantages, scope, and practical application to screening biological samples for organic residues are illustrated by reference to several published methods for pesticide residues and drugs.
