    摘要: A supercritical fluid chromatography system comprises a first pump for pumping a first flow stream comprising a compressible fluid and a second pump for pumping a second flow stream comprising a modifier fluid. The second pump is in parallel with the first pump. A column is located in a combined flow stream. The column is located downstream of the first and second pumps. The combined flow stream comprises the first flow stream, the second flow stream, and a sample. A detector is located downstream of the column. A gas-liquid separator is located downstream of the detector. The gas-liquid separator is configured to vent a majority of the compressible fluid while maintaining a majority of the sample, thus preventing aerosolization of the flow stream and minimizing sample loss as well as cross contamination. An open bed collector is located after the gas-liquid separator.

    摘要: A mixing device for use in a chromatography system, the device includes an exterior housing having a first end and a second end and a hydraulic flow connector at the first end of the exterior housing. A cartridge including a chamber is enclosed within the exterior housing. The chamber has at least one wall defining an interior volume having a shape, wherein the shape of the interior volume creates a turbulent flow condition to mix at least two fluids and provide flow through the cartridge during operation of the chromatography system. The chamber also retains the sample, thereby ensuring that the sample is focused in the chamber such that a more narrow bolus of sample enters the chromatography column.
