饮料级二氧化碳中痕量硫化物的分析
Abstract:
针对食品级二氧化碳中的ppb 级挥发性硫化物的分析，介绍了Agilent 6890 气相色谱仪上一种采用挥发性样品进样口的惰性进样阀系统，并描述了采用Agilent AED、FPD 和Sievers SCD 的应用案例；通过对含8 种硫化合物的CO2 混合物的检测，显示该系统对低硫含量样品的检测提供了易用的校正系统的方法。
An inert valving system using the volatiles interface (VI) on the Agilent 6890 is described for the analysis of ppb level volatile sulfur compounds in food grade carbon dioxide. Examples using the Agilent AED, FPD, and Sievers SCD are shown. The blending of CO2 with an eight component sulfur mix provides an easy to use means of calibrating the system for low level sulfur determinations.
