Abstract
Derivatization plays an important role in microanalysis by GC/SIM and is employed to enhance the GC-performance by involving the properties of derivatives in volatility and thermal stability. In addition, as the sensitivity and the specificity in microanalysis using GC/SIM is expected to enhance by choosing a derivative with a mass spectrum in which ion current is concentrated in a characteristic ion in high mass region, a number of new derivatives have been extensively examined for quantitation of endogenous substances and drugs in biological materials. This paper describes briefly our study on dimethylalkylsilyl ether derivatives and diethylhydrogensilyl-cyclic diethylsilylene derivatives and their application to microanalysis using GC/SIM.
