Application

Addition of Trimethylchlorosilane aids in the derivatization of amides, secondary amines and hindered hydroxy groups. Most volatile of the TMS derivatives often elutes at the solvent front of the GC.

General description

Silylation can be performed by adding N-Methyl-N-(trimethylsilyl)trifluoroacetamide (MTFA) during analysis of fluorometabolites via gas chromatography-mass spectrometry (GC-MS).

A novel method has been developed to simultaneously determine and quantify seven organic UV filters employing liquid (solid)-liquid extraction, derivatization with N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) and gas chromatography with mass spectrometric detection in various environmental matrices. The UV filters determined were:
