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 needle for aspirating a sample from a sample source and injecting the sample into a liquid chromatography system, the needle including a needle body having a rough textured surface finish for at least a portion of the needle body, wherein the rough textured surface finish reduces a coefficient of friction of the needle body, is provided. Furthermore, an associated method is also provided.
