• Analyses of trace impurities in SO2 were undertaken with the mass spectrometer and the gas chromatography. From the analyses of samples obtained from different commercial"high grade"SO2 bombs, the main components of trace impurities were estimated to be CO2, N2 and O2, in the order of magnitudes of 10<SUP>-3</SUP>%. In both qualitative and quantitative analyses of trace amount of N2 and O2 in SO2 gas chromatography with D. 0. P. on fire brick and molecular sieve 4A as columns, was superior to mass spectrometry with which O2 spectrum is obscured by the cracking patterns of SO2.
