A dual-sample cavity is described in which two samples can be placed and receive independent magnetic field modulation at 465 kc/s. When the two modulation fields are in anti-phase the spectrum recorded by the spectrometer is the difference between the individual spectra of the two samples. The technique has application in identification of spectra and in the separation of the individual spectra from a mixed material; examples are given of these applications.
