Abstract：
A mixing method of working gas Ar—CH₄—CH₂(OCH₃)₂ in SQS μ-counter model and a method of monitoring the concentration of CH₄, CH₂(OCH₃)₂ in working gas by chromatography are reported. Chromatographic column coated with 15% DNP and thermal conductivity detector are used in chromatography. Using gas sampling valve, sample of working gas in SQS μ-counter model is injected, then the chromatogram peak heights are measured, The concentration of CH₄ and CH₂(OCH₃)₂ are obtained by means of comparison with standard curves.
