Gas Chromatographic Analysis of Trace Benzene in Carbon Dioxide
Gas Chromatographic Analysis of Trace Benzene in Carbon Dioxide Details:

With economic development and technological progress, the supply and demand of "food additive liquid carbon dioxide" (hereinafter referred to as food CO2) has become increasingly tight. According to the per capita consumption of food CO2 in the United States, the annual demand for food CO2 in my country can reach 10,000 kt. Food CO2 The trace amount of benzene in the benzene seriously affects the quality of the product. The international food CO2 standard has strict requirements for the content of benzene: ≤0.02×10-6 (VN). At present, there is no such technical requirement in the domestic food CO2 standard, and it is expected to be issued in 2005 There will be provisions in the new version of the food CO2 national standard. There is no such national standard material in the analysis of trace benzene in food CO2 in my country. Therefore, research and development in this area are urgently needed to facilitate the transfer of quantity value.

For the determination of trace benzene at 20ppb, the traditional hydrogen flame detector can not determine it. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times and through the unremitting efforts of scientific researchers, successfully developed the determination of trace benzene in carbon dioxide. The high-sensitivity special gas chromatograph FID-GC, the sample is directly injected, and the benzene can be determined at 0.02ppm without enrichment. Welcome to consult and negotiate.
