Analytical method and performance evaluation method of benzene gas reference material in food additive carbon dioxide. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses GC- gas chromatograph and FID detector. Under the most JIA chromatographic experimental conditions, the detection limit of benzene is less than 10×10-9, and the linear error is less than 2%. The results of the uniformity, consistency, and stability (variation with time and pressure) of the benzene gas reference material in carbon dioxide are also given. The research results show that the relative expanded uncertainty of the weight preparation of the benzene gas standard substance in carbon dioxide is less than 1.7%.
