摘要：

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.
