摘要：
A new method has been developed for the quantitative determination of gas mixture composition where air penetration during gas sample collection would lead to erroneous results. It requires the use of a stationary phase that separates gas sample components and the air and involves 4–5 analyses of samples of equal volumes containing different amounts of air. By graphical extrapolation of the air peak area (Sair) as a function of the peak areas of the individual components (Scomp) the areas for these components in the absence of air can be obtained forSair=0.
