The prospect of an automated immunochemical detection system for on-line analysis of pesticide residues has important implications for environmental monitoring and control. Over the past seven years a flow injection immunoanalysis (FIIA) system was developed and optimized in our laboratories; this led to the development of a prototype of a flow injection immunoaffinity analysis (FIIAA) device. The strategy followed during this development is described here. First results of the newest version of this system are presented. The advantages and limitations of FIIAA compared with conventional analytical techniques, such as LC and GC/MS, microtiter plate ELISA, and the commercially available test-kits are also discussed. The currently undergoing demonstration for real water samples, and the potential of this FIIAA system for water monitoring will be outlined.
