摘要： A fractionated sample collection process and device having at least one pressurized chamber used to gather and store liquid samples generated from a flow stream containing a mixture of highly compressed gas, compressible liquid, or supercritical fluid and a relatively incompressible liquid. A bank of multiple collection chambers is secured together in a frame to form a cassette unit. Each collection chamber may house a replaceable liner such as a test tube vial, to hold a fractionated liquid phase sample. After filling with sample, a collection chamber is returned to a clean state and ready for refilling with a new sample by manually or automatically replacing the liner.

摘要： An efficient and safe method and apparatus for collecting exhaust gasses in an open-air sample collection container in a supercritical fluid chromatography system is claimed. The invention uses a vacuum force to evacuate the gaseous phase and vapors separated from liquid mobile phase in a sample collection device. The invention is portable to use on a series of collection containers, such as test tubes or wells in a titration place. Embodiments are claimed for capture of gasses and vapors either internally or externally to a collection container. The invention removes the gasses from the collection container that are then safely vented to a waste collector, thereby creating a safer environment for the laboratory and properly removing and disposing potentially hazardous chemicals instead of venting these chemicals into the environment.

摘要： A system for collection of liquid phase sample fractions from a supercritical fluid chromatography system is disclosed. The system has different ways of gathering the liquid phase into a collection chamber and provides for automated removal of liquid phase from a collection chamber into separate collection container. A separate pressure scheme is invoked upon the collection chambers to move liquid phase out of a chamber and into the separate collection container. In addition, the invention provides a renewal system for the collection chambers where each chamber returns to an uncontaminated stated by washing with a cleaning solution after removal of collected liquid phase. Spent cleaner from a chamber is purged using the pressure system into a waste stream for disposal.

摘要： The invention is a device and method in a high-pressure chromatography system, such as a supercritical fluid chromatography (SFC) system, that uses a pump as a pressure source for precision pumping of a compressible fluid. The preferred exemplary embodiment comprises a pressure regulation assembly installed downstream from a compressible fluid pump but prior to combining the compressible flow with a relatively incompressible modifier flow stream. The present invention allows the replacement of an high-grade SFC pump in the compressible fluid flow stream with an inexpensive and imprecise pump. The imprecise pump becomes capable of moving the compressible fluid flow stream in a precise flow rate and pattern. The assembly dampens the damaging effects of an imprecise pump, such as large pressure oscillations caused by flow ripples and noisy pressure signals that do not meet precise SFC pumping requirements.

摘要： A process and device for chromatography, such as preparative and analytical supercritical fluid chromatography, or supercritical fluid extraction for a liquid phase SFC collection system that separates and retains eluted components from sample injections. The process efficiently separates liquid and gas phases in the flow stream upstream of a collection vessel and without additional pressure schemes or solvent extractions imposed on the flowstream. Sample fractions are collected from sample component concentration peaks based upon the chromatographic elution of the sample components. Samples are repeatedly the injected into the mobile phase flow stream and collected into large volume collection containers, thereby allowing longer unattended run times and cost-efficient sample purification and recovery.

摘要： A method for converting a pump for use in a flow stream containing a mixture of highly compressed gas, compressible liquid or supercritical fluid wherein the pump delivers a compressible fluid against a back-pressure regulator which in turn delivers a controllable flow rate downstream of the regulator without performing variable compressibility compensation adjustments on the pump. By using a pressurized source of compressible fluid combined with isocratic conditions, the delivery pressure from the pump is controlled at a rate higher than the downstream gradient with the back-pressure regulator, and an inexpensive pump may be used in place of specialized, expensive pumps and compressibility compensation systems for use in stems operating at or near supercritical fluid levels of compressible fluids. Significant capital and operating laboratory costs are saved through a simpler and cheaper system for accurately delivering compressible fluids into mobile phase flow streams.
