    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. Ultra-high vacuum - Wikipedia

    en.wikipedia.org/wiki/Ultra-high_vacuum

    In the first stage, a roughing pump clears most of the gas from the chamber. This is followed by one or more vacuum pumps that operate at low pressures. Pumps commonly used in this second stage to achieve UHV include: Turbomolecular pumps (especially compound pumps which incorporate a molecular drag section and/or magnetic bearing types) Ion pumps

    The NEG acts as a getter or getter pump that is able to reduce the pressure to less than 10 −12 mbar. Non-evaporable getters , which work at high temperature, generally consist of a film of a special alloy, often primarily zirconium ; the requirement is that the alloy materials must form a passivation layer at room temperature which ...

    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. Ion trap - Wikipedia

    en.wikipedia.org/wiki/Ion_trap

    An ion trap, used for precision measurements of radium ions, inside a vacuum chamber. View ports surrounding the chamber allow laser light to be directed into the trap. An ion trap is a combination of electric and/or magnetic fields used to capture charged particles — known as ions — often in a

  9. Ion-mobility spectrometry–mass spectrometry - Wikipedia

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

    In 2013, Agilent Technologies released the first commercial drift tube ion mobility-mass spectrometer named 6560 with an 80 cm drift tube. Ion funnels are used to improve the ion transmission efficiency. The design thus greatly improved the sensitivity of ion mobility and allowed commercialization. [7]
