ABSTRACT:
A pyrolysis/desorption apparatus for use with chromatographic and spectroscopic detection systems for providing chemical analysis of samples. The device includes a tubular body having an interior reaction chamber which houses a pyrolysis/desorption probe adapted for bearing a coating of the sample composition to be analyzed. A separating tube is positioned within the reaction chamber, at a slightly displaced distance from the probe for receiving reaction product entrained within a carrier gas. A carrier gas inlet is coupled to the tubular body upstream from a portion of the reaction chamber and operates to introduce carrier gas flow through the reaction chamber and toward an opposing end of the tubular body. A carrier gas outlet is located down stream from the reaction chamber for venting carrier gas and entrained reaction products which are not split off by the separating tube. This separating tube is of substantially smaller cross section than the cross section of the reaction chamber to enable increased speed of analysis and increased control of product flow. The system is adapted with means for maintaining carrier gas flow at a speed greater than the back diffusion rate of possible contaminant materials within the tube which may exist down stream of the reaction chamber.
