A new method to measure oxygen concentration in air-saturated organic solvents and binary mixtures has been developed. The methodology relies on the ability of HPLC columns to retain the molecular oxygen contained in different types of solvents which are injected into the system at 298.15 K. The outlet of the HPLC is coupled with an optical oxygen sensor which continuously measures changes in oxygen partial pressure.
已经开发出一种测量空气饱和有机溶剂和二元混合物中氧浓度的新方法。该方法依赖于 HPLC 柱在 298.15 K 下保留注入系统中不同类型溶剂中所含分子氧的能力。HPLC 的出口与光学氧传感器相连,该传感器连续测量氧分压的变化。
