摘要： A pressure gauge mounted to a pump or a back pressure regulator in an HPLC, SFC, or SFE system provides improved solvent exchange and improved measurement precision. A through hole having an inside diameter of 1.0 mm is made in a hexagonal member similar in shape to a pipe joint. A part of the hexagonal member is cut away to form a flat surface such that the distance to the outside periphery of the through hole is 0.5 mm to serve as a strain-measurement strain gauge attaching surface. One strain gauge is attached to the center of the strain-measurement strain gauge attaching surface, and two strain gauges are attached for temperature correction, one on the same surface as the strain-measurement strain gauge attaching surface and the other on an outside surface of the hexagonal member.

摘要： There is provided a sample collection container, a sample collection apparatus, and a sample collection method used in a supercritical fluid system capable of collecting a multi-constituent sample contained in a supercritical fluid at low cost and high collection efficiency. The pressure of a supercritical fluid containing a sample is reduced to a pressure close to the atmospheric pressure, and the depressurized supercritical fluid is forced to undergo adiabatic expansion to form gas-phase CO 2 containing a liquid component in the form of aerosol. The gas-phase CO 2 is fractionated for each constituent of the contained sample, transferred to a probe 60 of Liquid Handler, and dispensed into a large number of collection vials 300 under the atmospheric pressure, each of which is provided with a vial cap 100. The aerosol-containing gas-phase CO 2 is sprayed through the tip of an introduction tube 210 provided in each of the vial cap 100 in a direction downwardly-inclined from the tangential direction along an inner circumferential surface 308 of the corresponding collection vial 300, and swirls and falls in the collection vial 300. In this process, the liquid component containing the sample collides with the inner circumferential surface 308 and is trapped thereon, whereas the gas-phase CO 2 is discharged out of a discharge hole 109 in the vial cap 100.
