Title:

SUPERCRITICAL FLUID PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/083639

Kind Code:

A1

Abstract:

A supercritical fluid chromatograph comprises a supercritical channel, a mobile phase supply unit to supply a mobile phase containing liquid carbon dioxide, a sample injection unit, a sample separation unit, a detecting device, and a pressure control valve. A valve post-stage channel is connected to a fluid exit of the pressure control valve, and the interior of the valve post-stage channel is maintained at a pressure, by way of a pressure maintaining means, at which the mobile phase from the fluid exit of the pressure control valve does not gasify.
