ABSTRACT:
This invention pertains to a novel plasma detector that is useful for the detection of compounds separated by gas chromatography. More particularly, the invention relates to a novel radio-frequency, atmospheric pressure capacitively coupled plasma torch which can be used as an element specific, spectroscopic detector for gas chromatography. A method of detecting compounds separated by gas chromatography comprising passing the gas product of a gas chromatograph through a radio-frequency atmospheric pressure capacitively coupled plasma and anaylzing the results.
