ABSTRACT:
A gas chromatograph system is provided with an improved electrolytic conductivity cell (16) for detecting a selected material species in a fluid stream from conventional gas chromatograph (10, 12) having both gas and liquid phases. Planar electrodes (80, 82) are spaced by an insulator (84) and define borehole diameters (88, 90, 92) which enhance the generated signal-to-noise ratio by providing a short fluid transit time within the conductivity detecting volume compared with the effective time of the chromatographic event of interest. A pneumatic damper (108) may be further included to reduce generated system signal noise.
