摘要: Abstract Isothermal retention indices of some dicarboxylic acid bis(trimethylsilyl) esters at four temperatures a non-polar capillary column with cross-linked polymethylsiloxane stationary phase are presented. The separation particular is discussed and the chromatographic behaviour compared that dimethyl esters. characteristic features electron impact methane isobutane chemical ionization mass spectra their usefulness for identification trimethylsilyl derivatives discussed.
