Abstract
The capabilities of a number of trimethylsilylating and trifluoroacetylating agents in gas chromatographic analysis of mixtures of type A and of type B trichothecenes have been compared. Problems encountered in the analysis are mainly concerned with the decomposition of the derivatives due to imperfect removal of the excess of reagents. The application of the volatile reagent, trifluoroacetic anhydride, in combination with the acid acceptor, sodium bicarbonate, was found to be the best choice.
