  2. Ion pump - Wikipedia

    en.wikipedia.org/wiki/Ion_pump

    A noble diode pump is a type of ion pump used in high-vacuum applications that employs both a chemically reactive cathode, such as titanium, and an additional cathode composed of tantalum. The tantalum cathode serves as a high-inertia crystal lattice structure for the reflection and burial of neutrals, increasing pumping effectiveness of inert ...

    Agilent Technologies, Inc. is an American global company headquartered in Santa Clara, California, that provides instruments, software, services, and consumables for laboratories. Agilent was established in 1999 as a spin-off from Hewlett-Packard .

  4. Ionic liquid piston compressor - Wikipedia

    en.wikipedia.org/wiki/Ionic_liquid_piston_compressor

    An ionic liquid piston compressor, ionic compressor or ionic liquid piston pump is a hydrogen compressor based on an ionic liquid piston instead of a metal piston as in a piston-metal diaphragm compressor.

  5. Getter - Wikipedia

    en.wikipedia.org/wiki/Getter

    Getter pump or sorption pump In laboratory vacuum systems, the bulk NEG getter is often held in a separate vessel with its own heater, attached to the vacuum system by a valve, so that it can be replaced or renewed when saturated. [8] Ion getter pump Uses a high voltage electrode to ionize the gas molecules and drive them into the getter surface.

    It also purchased HHV Pumps Pvt Ltd, a designer and manufacturer of vacuum pumps located in Bengalaru, India, for £10.9 million. Atlas Copco also agreed to purchase the assets of Chinese, liquid ring vacuum pump manufacturer Shandong Jinggong Pump Co Ltd, to join the Edwards vacuum pump business.

  8. Sorption pump - Wikipedia

    en.wikipedia.org/wiki/Sorption_pump

    The sorption pump is a cyclic pump and its cycle has 3 phases: sorption, desorption and regeneration. In the sorption phase the pump is actually used to create a vacuum. . This is achieved by cooling the pump body to low temperatures, typically by immersing it in a Dewar flask filled with liquid nitro

  9. Ion-mobility spectrometry–mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Ion-mobility_spectrometry...

    Earl W. McDaniel has been called the father of ion mobility mass spectrometry. [1] In the early 1960s, he coupled a low-field ion mobility drift cell to a sector mass spectrometer. [2] The combination of time-of-flight mass spectrometry and ion mobility spectrometry was pioneered in 1963 at Bell Labs. In 1963 McAfee and Edelson published an IMS ...
