Patent ID: 7306720

Claim:
A liquid chromatographic system comprising: (a) a liquid chromatographic column having an inlet and an outlet, (b) a suppressor comprising a sample stream flow channel having an inlet and an outlet and separated by a permselective membrane from a regenerant stream flow channel having an inlet and an outlet, said liquid chromatographic column outlet in fluidic communication with the inlet of the said suppressor sample stream flow channel (c) a volatile component-removal device comprising a membrane comprising at least one porous wall, said device defining a liquid sample stream flow channel, having an inlet and an outlet, on one side of said membrane, and a receiving channel on the other side of said porous wall, said volatile component liquid sample stream flow channel inlet being in fluid communication with said suppressor sample stream outlet, and (d) said suppressor regenerant stream flow channel outlet being in fluid communication with said receiving channel of the volatile component-removal device.
