  • Patent number: 10738918
    Abstract: A manifold assembly has a manifold and can be located between a block and a plate, and serve as a stator for a valve or other component. The manifold, block or plate can have a plurality of ports either integral thereto or removably connected thereto, with the ports adapted to receive and sealingly engage with a tube having an inner tube layer, an outer tube layer, a sleeve, a tip portion, and a nut. Each of the nut, sleeve, inner and outer tubing layers, and tip portion have a passageway therethrough, with at least the passageways in the sleeve, tip portion, outer tube layer, and nut adapted to allow the inner tube layer to pass therethrough or extend over the inner layer. The ends of the tip portion and inner layer together can define a substantially flat surface which can form a seal in a flat-bottomed port of the manifold, block, or plate, which can be used in a component in an analytical instrument system, including for example a liquid chromatography system.

  • Publication number: 20200164286
    Abstract: A membrane-based fluid degassing system is arranged for automated control to a degassing efficiency set point, so that fluid is degassed only as necessary. The control variable may be assigned as the degassing environment, to provide the gas transfer driving force suitable to appropriately degas the fluid. By avoiding unnecessary degassing of the fluid, mobile phase pervaporation through the membrane is minimized.

  • Patent number: 10520477
    Abstract: Valve with multi-piece stator assembly for use with liquid chromatography or other analytical systems. A separate and removable stator plate is provided with a mounting device to provide a multi-piece stator assembly. The mounting device is adapted on one side to engage and contact the stator plate, and on the other side includes a plurality of ports for fluidic connections which are in fluid communication with fluid passageways in the stator plate. By making the stator face a separate component, the overall costs of the valve can be reduced, different materials can be used for the mounting device and the stator, and the valve can be used for ultra-high pressure applications, including in liquid chromatography and other analytical instrument systems.

  • Publication number: 20190361394
    Abstract: A Volume Bragg grating (VBG) is placed in the back of a collimating lens, the incident angle between exposure light beam and the Volume Bragg grating is equal to the Bragg angle of the Volume Bragg grating. A photodetector is placed in the ?1 grade transmission diffraction light path of the Volume Bragg grating which the exposure light beam is emitted to. The pinhole filter is moved back and forth along an optical axis and the reading of the photodetector is observed in real time. When the reading of the photodetector is maximum, fix the pinhole filter and keep the distance between the first pinhole filter and the first collimating lens a constant. The method for adjusting the self-collimation optical path is provided, using the Volume Bragg grating to detect the parallelism of self-collimation light and substituting for a traditional Moire pattern adjustment method.
