    摘要： The invention provides chromatographic apparatus and components manufactured from a corrosion resistant alloy typically comprising iron, nickel, chromium and molybdenum. The apparatus and components exhibit superior biocompatibility and corrosion resistance, especially to mobile phases containing chlorides. They are especially useful in HPLC and HPLC, and are particularly useful in conjunction with chromatographic separation media comprising particles smaller than 2 μm diameter.

    摘要： 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.

    摘要： 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.
