✦ Synopsis
NOW analysis of the signal from a non-optical microwave plasma detector for gas chromatography IS presented The slgnal m this detector IS the reflected microwave power White noise, low-frequency l/f noise and high-frequency discrete noise were the major noise types observed m the frequency wmdow considered (O-200 Hz) The overall magnitude of the noise spectra exhibited a marked dependence on the degree of coupling of power to the microwave cavity and, to a lesser extent, on the flow-rate of the plasma gas The noise did not change consistently as the plasma tube cooling-water flow-rate was changed Keywords Gas chromatography, Microwave-induced plasma, Noise spectra, Plasmas
