食品级CO_2用于可口可乐等高级饮料作添加剂,要求总硫低于0.5ppm。 它的生产工艺为:焦炭造气→ADA脱硫→中变→水洗,水洗解析气(CO_2达99％以上)经脱硫、脱水加工成产品。

　　浩瀚色谱（山东）应用技术开发有限公司，研制检测食品用二氧化碳中总硫/二氧化硫装置及方法，装置设有一个四通阀，样气经四通阀后进入进样阀，测定被测食品用二氧化碳中的总硫含量；样气经四通阀和填装有脱除二氧化硫催化剂的脱二氧化硫管之后进入进样阀，用于测定被测食品用二氧化碳中的除二氧化硫外的总硫含量，通过总硫含量与除二氧化硫外的总硫含量的差值，得出二氧化硫的含量。

　　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. Its production process is as follows: coke gasification → ADA desulfurization → intermediate transformation → water washing, and the water washing analyzed gas (CO2 reaches over 99%) is processed into products through desulfurization and dehydration.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a device and method for detecting total sulfur/sulfur dioxide in food carbon dioxide. The device is equipped with a four-way valve, and the sample gas enters the injection valve after passing through the four-way valve to determine the total sulfur content in the tested food carbon dioxide; After passing through a four-way valve and a sulfur removal tube filled with a sulfur removal catalyst, the sample gas enters the injection valve to determine the total sulfur content in the tested food carbon dioxide, except for sulfur dioxide. The sulfur dioxide content is determined by the difference between the total sulfur content and the total sulfur content except for sulfur dioxide.

　　Name: Desulfur dioxide removal tube

　　Model: HH-SO2

　　Specification: 60mm * 3mm

　　*High operating temperature: 100 ° C

　　Number: 20240408001

　　Application: Total sulfur in food grade carbon dioxide/Total sulfur removed from sulfur dioxide

　　High removal efficiency, symmetrical peak shape, and satisfactory results.
