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 (36), cartridge housing (38), seal wash housing (40) and plunger (42). 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 (60) is displaced laterally from other drive assembly components but is coupled through a belt (110) and pulley system (102).

Abstract: A method for injecting a sample into a flow of a liquid chromatography system includes providing a flow of a mobile phase, and injecting a volume of a sample into the flow of the mobile phase such that the concentration of the sample within the mobile phase varies with a triangular profile over the course of the injecting.
