A sampling system was designed to permit the determination of the saturate, unsaturate, aromatic, and oxycarbon content of stationary-source hydrocarbon vapor emissions. A Joy Manufacturing Company Method 5 stack sampler was modified to incorporate a vapor collector cartridge that quantitatively traps all volatile hydrocarbons present in the sampled gas stream. The Class Analyzer desorbs the sample from this Universal Collector and passes it through a system of class abstractors that remove certain hydrocarbon classes while permitting the remainder of the sample to pass into cryogenic traps. The contents of each trap are desorbed sequentially through an external flame ionization detector. The quantity of each class present in the sample is calculated from the detector responses to the effluents from the various class abstractor streams. Detailed evaluations of the Universal Collector and class abstractor candidates are presented. Test results of the complete sampling and analytical system are included.
