Abstract: The difference in concentration of a selected isotope in two materials is measured by directing gaseous beams of the materials toward the inlet of a mass spectrometer. A shutter alternately blocks transmission of the two beams. An output signal from the mass spectrometer, which is representative of a selected isotope, is passed to a synchronous detector, as is a reference signal which is representative of the speed of operation of the shutter.

Abstract: In a chromatographic analyzer, the carrier fluid stream is split at a point downstream from the sample injection. A first portion of the stream is passed through the chromatographic column in a conventional manner. The second portion of the stream is passed directly to the detector to provide an indication of the amount of sample injected.
