A high through-put screening immunochemical method to control the presence of 2,4,6-trichloroanisol (TCA) and 2,4,6-tribromoanisol (TBA), the main agents responsible for the musty odor in wine samples, has been developed. The method involves a selective (antibody−antigen) solid-phase extraction (SPE), followed by enzyme-linked immunosorbent assay (ELISA) analysis. The sample preparation method established uses for immunosorbents (ISs) prepared by covalently coupling antibodies developed for TCA on a sepharose support. At present, about 200−400 ng L-1 of TBA and TCA can be detected in white wine samples by the IS-SPE-ELISA method described here without any preconcentration step. Simultaneous analyses of many samples are possible with this method. Related chloroanisoles (2,3- and 2,6-dichloroanisols and 2,3,4,5-tetrachloroanisol) and chlorophenols (2,3,4,6-tetrachlorophenol and pentachlorophenol) usually present in contaminated wine samples are also effectively retained by the IS, although only 2,4,6-TCA and 2,4,6-TBA are detected by the ELISA used. The immunopurification procedure developed could also be useful as a selective cleanup method prior to chromatographic analysis.
