Abstract
  • The change in the oscillation frequency in the current of an atmospheric helium glow discharge is a sensitive detector for gas chromatography. The response of the detector is in the femtomole and picomole range for nonane and decane. The effluent of a capillary column is directed into a glow discharge cell perpendicular to the axis of the platinum anode and cathode where the glow exists. This thesis describes the development of a glow discharge cell, the determination of the optimum operating parameters for a stable oscillating current, and then using those optimized conditions the determination of the linear relationship between the oscillating frequency and the concentration of the impurity in the cell.
