Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted research on the preparation method of trace gas reference materials for SO2 and COS in food additive carbon dioxide. The raw gas and dilution gas in the weight preparation process were analyzed and calibrated, and the experimental results and uncertainty evaluation results of purity analysis were provided. The experimental principle, method, and conditions of analyzing SO2 and COS gas reference materials using Haohan GC-790 gas chromatograph and flame photometric detector (FPD) were used. The precision and linearity of the chromatographic analysis method for the gas reference material were investigated using the established analysis method and conditions. The calculation method for evaluating the performance of the gas reference material and the concentration of each component were also provided. Experimental results of weight configuration expansion uncertainty within the range of (1.0~10.0) x 10-6 (mol/mol)
