    摘要： Described are techniques for force sensing. A computing device is configured to have a desired force setting. A first vertical position of a needle is determined using the computer device. A control signal is sent from the computing device to a positioning device. In response to the control signal, the needle is positioned at the first vertical position. When in the first vertical position, surfaces of a tip of the needle are in contact with surfaces of an opening of a sealing member and positioning the needle causes application of a force at surfaces of the opening in contact with surfaces of the tip of the needle. In response to application of the force, a spring is compressed a distance that is proportional to the force. The force is measured using a force sensor.

    摘要： Described is a compound sample needle for a liquid chromatography system. In one embodiment, the compound sample needle includes a rigid needle having a coupling end with a face and a counterbore. The compound sample needle also includes a flexible tubing having an outer surface and a coupling end disposed in the counterbore of the rigid needle. The coupling end of the flexible tubing has a face adjacent to a base of the counterbore. The coupling ends of the rigid needle and flexible tubing are secured to each other by a weld formed along a circumference of the outer surface and the face of the rigid needle. A rigid sleeve protects the welded joint. The compound sample needle is suitable for injection into the high pressure mobile phase of ultra performance liquid chromatography systems.

    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.
