We developed a supercritical fluid jet technique, which enables the vaporization and the jet-cooling of non-vola-tile molecules by supersonic expansion of their supercritical solutions to vacuum directly. For its purpose, a new high-pressure pulsed valve was developed. By using this pulsed valve, we could introduce the high-pressure fluid. over 25MPa into vacuum as a short gaseous pulse, and confirmed that we can obtain an enough jet-cooling condi-tion. In this review, we will introduce a detail of the high-pressure pulsed valve and its application for the super-critical fluid jet spectroscopy.
