ABSTRACT:
A chromatograph includes an inlet for receiving a sample and a pressurized carrier fluid flow and in response providing a sample/fluid mixture; a separation column located in a temperature-controlled zone 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; and a gas recycling system for receiving the detector output stream, and optionally a split flow and a septum purge line flow, and for providing therefrom a recycled carrier gas stream suitable for reuse as the pressurized carrier fluid flow.
