Abstract: Described is a solvent manager for a liquid chromatography system. The solvent manager includes a temperature control module, a plurality of solvent reservoirs, a gradient proportioning valve and a degasser. The temperature control module maintains a substantially constant temperature of one or more of the plurality of solvent reservoirs, gradient proportioning valve and degasser. The temperature control module may include a thermal chamber having an enclosure with a thermally controlled internal environment and may also include an active thermal element such as one or more heaters. The enclosure may surround at least one of the plurality of solvent reservoirs, gradient proportioning valve and degasser. The temperature control module reduces the negative effects on solvent composition that result from temperature-dependent changes in solvent viscosities and solvent densities. Such changes affect the retention times of analytes eluted from the chromatographic column.

Abstract: A method for regulating a volume of liquid delivered by a peristaltic pump includes: sensing an ambient temperature of the peristaltic pump (220), determining at least one of a motor speed and a motor operation duration based on the sensed ambient temperature (230), and operating the pump motor at a determined motor speed or motor operation duration to deliver a selected volume of liquid from the peristaltic pump (240). A peristaltic pump system with the necessary structural features to perform this method is also disclosed.
