    Abstract: A thermal module for pre-heating liquid flowing into a liquid chromatography column, includes a trough compartment with two ends, one of the two ends having an electrical socket, a first fluidic assembly, a second fluidic assembly, and a clamp assembly. The clamp assembly includes a rail configured to receive the first fluidic assembly. The clamp assembly includes a carriage slidably mounted to the rail and configured to receive the second fluidic assembly. The carriage is operable to establish a first fluid tight seal between the first fluidic assembly and a chromatography column received within the clamp assembly, and to establish a second fluid tight seal between the second fluidic assembly and the chromatography column. The clamp assembly is disposed within the trough compartment, and the first fluidic assembly is plugged into the electrical socket at the one end of the trough compartment.

    Abstract: Embodiments of the present invention feature devices and methods for holding fluids at high pressures. One embodiment of the present invention features a fluid containing conveying device for receiving and discharging fluids. The device comprises a housing having a chamber for containing a fluid. The housing has a first gasket receiving surface for receiving a gasket. A gasket formed of a deformable material and having a first abutment surface and second abutment surface. The first abutment surface received on the first gasket receiving surface and the second abutment surface for receiving a chamber closing piece. The chamber closing piece having a second gasket receiving surface, the chamber closing piece for closing the chamber. At least one of the first gasket receiving surface of the housing and the second gasket receiving surface of the chamber closing piece having a retaining grove, having at least one edge. Compression means for compressing the gasket, deforming the material such that the gasket is pressed into retaining groove and gripped by the edge of the cavity to prevent gasket movement.

    Abstract: Described are a method and an apparatus for delivering a fluid having a desired mass composition. According to the method, temperatures of the fluids to be mixed are sensed and the densities of the fluids at the sensed temperatures are determined. The volume of each fluid is determined so that a mixture of the fluids at the sensed temperatures has the desired mass composition. The determined volumes of the fluids are combined to create the mixture. In one option, combining the determined volumes includes metering flows of the fluids sequentially into a common fluid channel. Alternatively, combining the determined volumes includes controlling a flow rate of each of the fluids and directing the fluids into a common fluid channel.

    Abstract: To heat a flowing liquid, an apparatus includes a heater block assembly having a heater block made of thermally conductive material. The heater block assembly has a tube inlet, a tube outlet, and a tube path between the tube inlet and tube outlet. Tubing extends through the tube path from the tube inlet to the tube outlet. The tubing is in thermal communication with the heater block. A heater cartridge, in thermal communication with the heater block, is configured to provide heat to the heater block for transfer to liquid flowing through the tubing between the tube inlet and the tube outlet of the heater block assembly. Circuitry is in electrical communication with the heater cartridge to control a temperature of the heater block by controlling operation of the heater cartridge.
