  • Patent number: 11913685
    Abstract: Provided is a chiller and system that may be utilized in a supercritical fluid chromatography method, wherein a non-polar solvent may replace a portion or all of a polar solvent for the purpose of separating or extracting desired sample molecules from a combined sample/solvent stream. The system may reduce the amount of polar solvent necessary for chromatographic separation and/or extraction of desired samples. The system may incorporate a supercritical fluid chiller, a supercritical fluid pressure-equalizing vessel and a supercritical fluid cyclonic separator. The supercritical fluid chiller allows for efficient and consistent pumping of liquid-phase gases employing off-the-shelf HPLC pumps. The pressure equalizing vessel allows the use of off-the-shelf HPLC column cartridges. The system may further incorporate the use of one or more disposable cartridges containing silica gel or other suitable medium.

  • Publication number: 20240042460
    Abstract: A gas-liquid separator system that can effectively and efficiently separate liquid from a streaming mixture having a liquid portion and a gas portion. The gas-liquid separator may be used in supercritical fluid chromatography application where an analyte is separated from a carrier gas, such as carbon dioxide. A streaming mixture is dispensed into a separation chamber formed by a spindle shaft configured inside of a shroud cavity. The shroud cavity has a plurality of concave channels along the inner surface and extend down to an outlet end. The concave channels create pressure variations that promote the liquid portion to condense onto the inner surface of the shroud and flow down to the exhaust port. A spherical collection portion is configured on the outlet of the shroud and the condensed liquid flows thereover and down along a cone portion and off the cone tip.

  • Patent number: 10765968
    Abstract: Provided is a supercritical fluid chromatography method, system, and components comprising such a system wherein a non-polar solvent may replace a portion or all of a polar solvent for the purpose of separating or extracting desired sample molecules from a combined sample/solvent stream. The method and system are designed to eliminate or reduce the amount of polar solvent necessary for chromatographic separation and/or extraction of desired samples to less than or equal to twenty percent polar solvent within the total volume concentration of the total solvents used, and the technique may include one or more of a supercritical fluid chiller, a supercritical fluid pressure-equalizing vessel, and a supercritical fluid cyclonic separator. The supercritical fluid chiller and the use of the chiller allow efficient and consistent pumping of liquid-phase gases employing off-the-shelf HPLC pumps in the supercritical chromatography system using liquid-phase gas mobile phase.
