Analysis method and performance evaluation method of benzene gas standard substance in food additive carbon dioxide. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses hohanGC gas chromatograph and FID detector. Under the optimal chromatographic experimental conditions, the detection limit of benzene is less than 10×10-9, and the linearity error is less than 2%. The inspection results of the homogeneity, consistency and stability (variation with time and pressure) of the benzene gas standard material in carbon dioxide are also given. The research results show that the relative expanded uncertainty of benzene gas standard material weight preparation in carbon dioxide is less than 1.7%.
