Two stage derivatization with N-/tert.-butyldimethylsilyl/- N-methyl-trifluoroacetamide -MTBSTFA- and N-methyl-bis-/trifluoroacetamide/ -MBTFA- for the gas-chromatographic analysis of OH-, SH- and NH-compounds

Various alcohols, thiols, phenols, carboxylic acids, amines and amides were subjected to silylation with MTBSTFA followed by trifluoroacetylation with MBTFA. The reaction products have been identified and quantified by means of gas chromatography coupled with atomic emission and mass spectrometric detection.
