Summary

An oxygen analyzer using magnetic dipole transitions in conjunction with GaAIAs diode laser radiation at 763 nm with a response time of 10 ms is described. The lowest observable concentration is determined by optical noise. With a 7.2 m White cell, a detection limit of 500 ppm of oxygen is found for integrative and derivative spectroscopy.
