The preparation method of SO2 and COS trace gas standard substances in food additive carbon dioxide was studied, the raw material gas and diluent gas in the weight preparation process were analyzed and determined, and the experimental results and uncertainty evaluation of purity analysis were given. result.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. introduced the experimental principle, method and conditions of using GC-FPD gas chromatograph and flame photometric detector (FPD) to analyze SO2 and COS gas standard substances. The precision and linearity of the chromatographic analysis method for the gas standard substance were investigated by the established analytical method and conditions. The calculation method of the performance evaluation of the gas standard material and the experimental results of the expanded uncertainty of the weight preparation in the range of (1.0~10.0)×10-6 by the mole fraction of each component are also given.
