Static Headspace Analysis

For determining 22 volatile organic compounds in the atmospheric air, the operating modes of the gas chromatographic complexes «chromatography-mass spectrometer — two-stage thermodesorber» and «gas chromatograph with 2 FID — static headspace analysis sampler» are optimized. The modes provide the values of the separation coefficients of the chromatographic peaks in the range of 1.5 ÷ 21. It has been experimentally established that the highest desorption efficiency of volatile organic compounds is registered when the sample is concentrated into Tenax TA sorption tubes.
