ABSTRACT:
A gas chromatographic detector for detection of compounds which fluoresce as a photo-response to light. The detector utilizes a remotely located light source for fluorescent excitation of a compound in a gas phase, and includes apparatus for the measurement of emitted fluorescence of a gas and for the measurement of transmitted light through a gas. The detector is close-coupled to an output end of a heated chromatographic column and eliminates the requirement of heated transfer tubes between the column and the detector.
