Abstract
In a method of measuring substances each exhibiting a derivative peak of the phase sensitive detector (PSD) output at a pair of specific magnetic field intensities by sweeping the field, the magnetic field is switched between the specific magnetic field intensities to obtain only the absorptions at the specific field intensities to thereby substantially reduce the sweeping time as well as to reduce the background drift.
