A rapid method was developed for quantitative analysis of organotin compounds in mussels and sediments by fused silica capillary gas chromatography/mass spectrometry (GC/MS). The samples were homogenised with n-hexane and the organotin compounds were pentylated via Grignard reaction with pentylmagnesium bromide in ethyl ether. The mass spectrometer was used in SIM mode (Selected Ion Monitoring) to enable the simultaneous determination of more than twenty compounds. Recoveries of the organotin compounds were about 85-98% form mussel tissues and sediment samples. The detection limits were 0.05-0.08 µg/g in mussel tissues and 0.03-0.06 µg/g in sediments. This technique was developed in response to our need to process large numbers of environmental samples with a minimum time investment.

Abstract

A rapid method was developed for quantitative analysis of organotin compounds in mussels and sediments by fused silica capillary gas chromatography/mass spectrometry (GC/MS). The samples were homogenised with n-hexane and the organotin compounds were pentylated via Grignard reaction with pentylmagnesium bromide in ethyl ether. The mass spectrometer was used in SIM mode (Selected Ion Monitoring) to enable the simultaneous determination of more than twenty compounds. Recoveries of the organotin compounds were about 85-98% form mussel tissues and sediment samples. The detection limits were 0.05-0.08 µg/g in mussel tissues and 0.03-0.06 µg/g in sediments. This technique was developed in response to our need to process large numbers of environmental samples with a minimum time investment.
