  2. Agilent Technologies - Wikipedia

    en.wikipedia.org/wiki/Agilent_Technologies

    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. The resulting IPO of Agilent stock was the largest in the history of Silicon Valley at the time.

  3. 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 ...

  4. 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

  5. Varian, Inc. - Wikipedia

    en.wikipedia.org/wiki/Varian,_Inc.

    Varian was spun off from Varian Associates in 1999 and was purchased by Agilent Technologies in May 2010 for $1.5 billion, or $52 per share. [ 2 ] Varian Inc. had its corporate headquarters in Palo Alto , California , and offices in Australia, the Benelux countries, Brazil, Canada, China, Germany, France, Italy, Japan, Korea, Russia, Sweden ...

  6. Ion source - Wikipedia

    en.wikipedia.org/wiki/Ion_source

    A duoplasmatron is a type of glow discharge ion source that consists of a hot cathode or cold cathode that produces a plasma that is used to ionize a gas. [1] [22] THey can produce positive or negative ions. [23] They are used for secondary ion mass spectrometry, ion beam etching, and high-energy physics. [24] [25] [26]

  7. Inductively coupled plasma mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Inductively_coupled_plasma...

    Examples include the Einzel lens, the Barrel lens, Agilent's Omega Lens [19] and Perkin-Elmer's Shadow Stop. [20] Another approach is to use ion guides (quadrupoles, hexapoles, or octopoles) to guide the ions into mass analyzer along a path away from the trajectory of photons or neutral particles.

  8. Turbomolecular pump - Wikipedia

    en.wikipedia.org/wiki/Turbomolecular_pump

    Interior view of a turbomolecular pump. A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [1] [2] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface.

  9. Cheng rotation vane - Wikipedia

    en.wikipedia.org/wiki/Cheng_rotation_vane

    A fluid flow conditioning device, the cheng rotation vane (CRV) is a stationary vane [1] fabricated within a pipe piece as a single unit and welded directly upstream of an elbow before the pump inlet, flow meters, compressors, or other downstream equipment.
