Three kinds of isomers of cresol trimethylsilyl ethers were analyzed using a gas chromatograph-chemical ionization mass spectrometer with mass fragmentography technique to find any difference between these isomers in various conditions, such as reagent gases(anmonia, methane and iso-butane)and the ion source temperature(200°C∼290°C). With anmonia as a reagent gas, the peak intensity ratios of m/e 180 to m/e 181 show remarkable differences between m-, o-and p-cresol trimethylsilyl ethers at 290°C of the ion source temperature.
