Described is an interface module for robotic loading and unloading of a liquid chromatography sample manager. The module includes a transfer drawer receiving apparatus having a device track and a drawer drive system configured to transport a transfer drawer along the device track into and out from a sample tray of a sample manager. The transfer drawer receives a sample-vial carrier that holds samples to be analyzed. The module further includes a window apparatus that has a window controllable to be in an open state or a closed state. When in the open state, transport of the transfer drawer through the window into or out from the sample manager permits loading of the sample-vial carrier into the sample tray and unloading of the sample-vial carrier from the sample tray. In the closed state, the window apparatus substantially seals the internal environment of the sample manager from the ambient environment.

The technology generally relates to tailoring a back pressure regulator in a chromatographic system to reduce unswept volume within the back pressure regulator to achieve better sample detection and a reduction in chromatographic band distortion effects.

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.
