Direct gas chromatographie determination of organotins as halide forms [Détermination des organoétains par injection directe sous forme d'halogénures et chromatographie gazeuse]

Abstract

cited By 6International audienceA critical review of procedures for the determination of organotin compounds in standards and natural samples (waters, sediments, biological matrices) without derivatization step has been carried out from 47 references. After acidification and extraction from sample, organotins as halides are directly injected into the gas chromatograph (GC). Operating conditions have been reported and compared for each experimental step. The stability of organotin halides in solution and during the chromatographic analysis has been described. Several detections methods have been used by the authors. Flame photometry (FPD) has been submitted to particular examination. Detection limits have been compared according to the type of detection. Finally, the abilities and limits of the direct chromatographie determination of organoiin halides have been established from the bibliography. © 1995 Elsevier, Paris
