Measurement of O2(1Δ) content in the gaseous effluents of a chemical generator

Abstract
A ratiometric system for accurately determining the percent O(2)((1)Delta) in a low-pressure gas sample has been developed and calibrated by use of a secondary microwave standard source and EPR measurements. The advantages of the new system over EPR are low cost and the ability to continuously monitor rapidly changing concentrations of O(2)((1)Delta).
