Analysis of Dithiocarbamate Pesticides by GC-MS

Instrument Type: GCMS

The class of dithiocarbamate fungicides (DTCs) is widely used in agriculture. They are non-systemic and both the formulation and their break-down products typically remain at the site of application. DTCs exhibit a broad spectrum of activity against various plant pathogens, low acute mammal toxicity, and low production costs. DTC are highly unstable so they can be quantitatively converted to carbon disulphide by reaction with tin(II)chloride in aqueous HCl (1 : 1) at 80 °C. The CS2 gas produced is absorbed into iso-octane and measured by GC-MS as described in this application.
