Supercritical fluid extraction apparatus and method or supercritical fluid chromatography

摘要

(57) (11), elongated and includes a supply tube for the fluid pressure above its critical pressure, the inner and outer surfaces, the proximal and distal aperture variable orifice fluid to be used in conjunction with chromatography Bluff or [summary] supercritical extractor I and a tubular probe. The proximal end of the probe being disposed toward the inlet pipe. The end of the probe, the adjustable orifice means having an orifice member of the first and second and is adapted to be dispensed fluid and (1240), an adjustment shaft portion having an end portion of the first and second I have a. Adjustable orifice means (1240) is adjacent to the outer surface of the probe, the orifice means (1240) is adjusted by adjusting the shaft portion. End of the shaft portion, the fluid is disposed at the distal end of the probe, moves with respect to the orifice member of the second orifice member first, by controlling an adjustable orifice (1240) through the (1240) adjustable orifice I vary the amount of squeezing.
