Pressure control apparatus for supercritical fluid |
| abstract |
An object of the present invention is to provide a pressure control apparatus for a supercritical fluid in which variation in pressure is small even in measurement in which analysis conditions are changed with time to improve separation and other performance. n That is, a pressure control apparatus for a supercritical fluid according to the present invention includes: a valve comprising; a valve chamber provided in a midway of a channel through which a supercritical fluid passes; and an electrically-operated valve element located in the valve chamber; wherein a front end of the valve element fits into the valve chamber when the valve is closed, and it travels backward when the valve is opened; a pressure detection member for detecting the pressure of the supercritical fluid in the channel on an upstream or downstream side of the valve chamber; an open/close control member for controlling the pressure detected by the pressure detection member to be a target pressure; and a valve-opening rate adjustment member for adjusting the valve-opening rate when the valve is opened based on the state of the supercritical fluid. |
