Speciation analysis of organotin in water and sediments by gas chromatography with optical spectrometric detection after extraction separation
Résumé
The state of the art of gas chromatography with atomic emission and atomic absorption spectrometric detection as a technique for speciation analysis of organotin in water samples and sediments is discussed. Extraction separation of ionic organotin compounds and their conversion to gas chromatographable species are reviewed. Recent advances in instrumentation with respect to sensitivity, selectivity and applicability to real sample analysis are highlighted. Particular emphasis is given to sources of error and accuracy of the data obtained.
