Abstract:
A back pressure valve configured to switch between a pressurized state and a released state open to an atmosphere is used as a back pressure valve in a supercritical fluid chromatograph. Switching from a state of supercritical fluid chromatography analysis to liquid chromatography is performed by stopping a pump that supplies a supercritical fluid, continuously operating a pump that supplies a solvent used as a modifier, and bringing the back pressure valve into the released state.
