Abstract: Described is a metering pump that may be used to meter volumes of sample in a chromatography system. The metering pump has a modular configuration that allows for separation of a head pod from a drive assembly for easy serviceability. The head pod includes a pump head, cartridge housing, seal wash housing and plunger. The drive assembly can be implemented in an inline drive configuration. Alternatively, the drive assembly can be implemented in an offset drive configuration in which a stepper motor is displaced laterally from other drive assembly components but is coupled through a belt and pulley system.

Abstract: A liquid chromatography sample manager includes a thermal chamber, a sample platter mounted in the thermal chamber, and a needle drive including a base having a shaft configured to rotate about a vertical axis, the base attachable to an interior of a sample manager of a liquid chromatography system. The needle drive further includes a needle assembly attached to the base, the needle assembly including a sample needle, and a drive system attached to the base, the drive system including a sample needle motor configured to impart vertical movement of the sample needle. The liquid chromatography sample manager further includes a sample delivery system configured to transfer a first sample from a first sample vial carrier located in the sample platter into a chromatographic flow stream.

Abstract: A liquid chromatography sample organizer includes a first chamber, a plurality of stacked sample organizer shelves mounted within the first chamber each individually configured to store a sample-vial carrier including a sample, and a shelf magnet affixed to a surface of each of the plurality of stacked sample organizer shelves. A portion of the first chamber is configured to be located adjacent to, and open to, a sample manager configured to inject liquid chromatography samples into a chromatographic flow stream. Disclosed further is a liquid chromatography system having the sample organizer, a sample drawer, and a method of transferring samples between a sample manager and the sample organizer.
