在食品级液体二氧化碳生产过程中,由于硫化物成分的复杂性和多样性,均会直接或通过反应对食品产生令人讨厌的气味.食品级CO2用于可口可乐等高级饮料作添加剂,要求总硫低于0.5ppm。

　　为适应产品中总硫含量＜0.1 mg/m3的新要求，浩瀚色谱（山东）应用技术开发有限公司进行了火焰光度检测器(FPD)的色谱法分析工业与食品级二氧化碳中微量硫的分析检测实践.论述了二氧化碳中微量硫化物的分析检测方法、分析试验技术参数的确定以及微量硫分析检测实践。

　　In the production process of food grade liquid carbon dioxide, due to the complexity and diversity of sulfide components, unpleasant odors can be directly or through reactions on food. Food grade CO2 is used as an additive in high-end beverages such as Coca Cola, with a total sulfur requirement of less than 0.5ppm.

　　In order to meet the new requirement of a total sulfur content of less than 0.1 mg/m3 in products, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has conducted chromatographic analysis of trace sulfur in industrial and food grade carbon dioxide using flame photometric detectors (FPD). The analysis and detection methods of trace sulfur in carbon dioxide, determination of analytical test technical parameters, and practice of trace sulfur analysis and detection are discussed.
