随着经济的发展和科技的进步,"食品添加剂液体二氧化碳"(以下简称食品CO2)的供求日趋紧张.按照美国食品CO2的人均消费量,我国食品CO2的年需求量可达10000 kt.食品CO2中的微量苯严重影响产品质量,国际食品CO2标准中对苯的含量有严格要求:≤0.02×10-6(VN).目前国内的食品CO2标准中尚无此项技术要求,预计2005年颁发的新版食品CO2国标中将有规定.食品CO2中微量苯的分析中我国尚无该类国家级标准物质,因此亟待在此方面进行研究和开发,以利于量值传递.

针对20ppb的痕量苯的测定，传统氢火焰检测器根本无法测定，浩瀚色谱（山东）应用技术开发有限公司，，经过科研人员的不懈努力，成功研制出二氧化碳中痕量苯测定的高灵敏度专用气相色谱仪FID-GC，样品直接进样，无需富集，即可测定0.02ppm的苯，欢迎咨询洽谈。

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.
