摘要:
A sample concentrator for concentrating analytes in a solvent-containing liquid sample stream, including concentrator housing having a sample stream flow channel and a gas stream flow channel having an inlet and an outlet, a heater for gas in the gas stream conduit, and a hydrophilic ion exchange or non-ionic membrane barrier separating said gas stream flow channel and said sample stream flow channel. Solvent is evaporated from the liquid sample stream in said sample stream flow channel in or at the interface with said membrane, when the gas stream is at an elevated temperature. A regeneration step is used to regenerate the ion exchange membrane barrier.
