A gas chromatographic method for the separation and quantitation of the 20 protein amino acids is described using N-methyl-N(tert.-butyldimethylsilyl)trinuoroacetamide, with 1% tert.butyldimethylchlorosilane as catalyst, to prepare the tert.-butyldimethylsilyl amino acid derivatives. Alkylsilylation
Quinoxalinol t-butyldimethylsilyl ethers were prepared from three branched-chain and from two aliphatic unbranched 2-keto acids. The electrou impact (EL) mass spectra display pronounced [M-57]+ ions. With 39-51'/0 of total ion current contained within them, sensitivity is greater than on chemical io
