Mass spectra of trimethylsilyl ethers of ethylene glycol, propane-1, 2-diol, butane-2, 3-diol (meso), propane-1, 3-diol, butane-1, 3-diol, butane-1, 4-diol, pentane-1, 5-diol and glycerol were obtained by GC-MS method. The base peak ions of these mass spectra were at m/e 147 in the ethers except those of butane-2, 3-diol and glycerol, which were observed at m/e 117 and 205 respectively. Other features of the spectra were discussed in relation to the molecular weight and structure. GC-MS method was useful for identification of the ethers.
