Abstract:
1. A system for concentrating and analyzing a gaseous sample, the system comprising: a separatory column; a pressurizer for compressing a gaseous sample from a first volume to a second volume, the second volume being smaller than the first volume, the pressurizer being fluidly connected to and upstream of the separatory column; a first sample passageway fluidly connected to and downstream of the separatory column; a second sample passageway fluidly connected to and downstream of the separatory column and fluidly connected to the first sample passageway, the second sample passageway including a flow restrictor that inhibits gas from flowing through the second sample passageway; a pressure-increasing valve arrangement fluidly connected to and downstream of the separatory column, which valve arrangement automatically one or more detectors located to receive analytes from at least the first sample passageway and to detect analytes delivered to the detector from the first sample passageway.
