Abstract

See full text

Described is an apparatus for controlling a position of a sample in a liquid chromatography system. The apparatus includes a rotary drive mechanism, a stepper motor and a rotational coupling system such as a drive belt and pulley system. The rotational coupling system transfers the rotational motion of a motor shaft to a shaft of the rotary drive mechanism. Advantageously, the stepper motor is remote to the sample compartment for improved safety in the event that volatile gas accumulates within the sample compartment. The rotary drive mechanism can be configured in a small form factor and can provide highly stable rotation of an attached sample tray to accommodate the requirements of compact liquid chromatography systems. In addition, leakage from inside the sample compartment to the ambient environment is substantially reduced or eliminated, resulting in better thermal control of the sample compartment.
