Organotins, such as tributyl tin (TBT) and triphenyl tin (TPT), are widely used as antifouling paint on ships and fishing nets. However, they cause problems with contamination of sea water and shell fish. Conventionally, GC-FPD has been used for the analysis of these compounds. Below, analysis using highly accurate GC/MS is introduced.

SIM Chromatogram of TBT in Sea Perch

Gas Chromatograph Mass Spectrometer

This instrument is widely used for the qualitative and quantitative analysis of chemical substances. The column and ionization method are selected to suit the analysis target.
