The determination of oxygen content in the air is a very classic inquiry experiment in the chemistry textbook published by the People's Education Press. Although the textbook has been revised and revised for many times, it always uses red phosphorus as the experimental drug to determine the oxygen content in the air. The author found that red phosphorus is prone to deliquescence during storage, and red phosphorus taken out of reagent bottles is often wet. It takes a long time to ignite red phosphorus, During the process of putting the red phosphorus burning in the combustion spoon into the gas collecting cylinder, P_ 2O_ It inevitably diffuses into the air



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatographic method for the determination of oxygen in the air, with high column efficiency, good separation and satisfactory results.
