ABSTRACT:
A preparative-scale gas chromatographic system has conduits and valves adapted for analysis and collection of low volatility effluent. An injection site is provided for alternately supplying liquid solvent for removing condensed effluent from the system when the flow of effluent is terminated. Conduits are joined within the thermal conductivity detector of the system to prevent condensation at the joint. Conduits are provided with copper jackets which are coupled to sources of thermal energy to prevent condensation within the conduits. A trap filter provides backpressure in the collection system wherein recovery of condensed effluent in the filter is facilitated by the smooth surface of the filter.
