Abstract:
A chromatograph for analysis of an analyte, comprising:an inlet for receiving a hydrogen gas stream and a sample containing the analyte, and in response, providing a sample/fluid mixture;a separation column connected to the inlet for receiving the sample/fluid mixture and for providing a column effluent stream;a detector for receiving the effluent stream and for providing a detector output stream, whereby the detector provides a detector signal representative of a characteristic of the analyte; anda gas storage system for receiving an incoming gas stream provided in the form of the detector output stream and a portion of the hydrogen gas stream not present in the sample/fluid mixture, filtering the incoming gas stream to provide a filtered stream, and storing the filtered stream so as to retain a conserved quantity of hydrogen gas suitable for reuse in the chromatograph as the hydrogen gas stream.
