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.
Ion pumps are commonly used in ultra-high vacuum (UHV) systems, as they can attain ultimate pressures less than 10 −11 mbar. [1] In contrast to other common UHV pumps, such as turbomolecular pumps and diffusion pumps, ion pumps have no moving parts and use no oil. They are therefore clean, need little maintenance, and produce no vibrations.
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 ...
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; Titanium sublimation pumps; Non-evaporable getter (NEG) pumps; Cryopumps
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 ...
This problem can be solved by purging the vacuum system with dry pure nitrogen before pump down. In purged system with aspirator rough pumping ultimate pressures of 10 −4 mbar for a single sorption pump and 10 −7 mbar for sequential pumping can be reached. [3] A typical source of dry pure nitrogen would be a liquid nitrogen Dewar head space.
Advanced Design System (ADS) is an electronic design automation software system produced by PathWave Design, a division of Keysight Technologies. [1] It provides an integrated design environment to designers of RF electronic products such as mobile phones , [ 2 ] pagers, wireless networks , satellite communications, radar systems, and high ...
Bruker Corporation is an American manufacturer of scientific instruments for molecular and materials research, as well as for industrial and applied analysis. It is headquartered in Billerica, Massachusetts, and is the publicly traded parent company of Bruker Scientific Instruments (Bruker AXS, Bruker BioSpin, Bruker Daltonics and Bruker Optics) and Bruker Energy & Supercon Technologies (BEST ...
