Abstract
A method for measuring the amount of oxygen in a sample gas is suited for quantifying small amount of oxygen in a sample gas. The method of the present invention comprises reacting the oxygen and vapor of yellow phosphorus under a vapor pressure of the yellow phosphorus which is lower than the saturated vapor pressure of the yellow phosphorus at room temperature; and measuring the intensity of light emitted by the reaction. The amount of the oxygen in the sample gas is determined by measuring the intensity of the light emitted by the reaction by a light intensity-measuring device.
