Russell gained patents for technology related to nuclear magnetic resonance (NMR), [23] [24] [25] as used in magnetic resonance imaging (MRI), thermionic tubes, and various radar technologies. [3] [15] Sigurd's inventions, some of which he patented, included a system of pumps, filters, and heaters for his swimming pool, as well as a high-speed ...
In 2008, Varian bought Oxford Diffraction, a British company specializing in X-ray diffraction equipment. On 27 July 2009, Agilent Technologies announced it would buy Varian Inc, for $1.5 Billion. On 14 October 2014, Agilent made the strategic decision to close its NMR business. Agilent entered the NMR business in 2010, with the acquisition of ...
NMR is extensively used in medicine in the form of magnetic resonance imaging. NMR is widely used in organic chemistry and industrially mainly for analysis of chemicals. The technique is also used to measure the ratio between water and fat in foods, monitor the flow of corrosive fluids in pipes, or to study molecular structures such as ...
Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
The Russell Varian Prize was an international scientific prize awarded for a single, high-impact and innovative contribution in the field of nuclear magnetic resonance (NMR), that laid the foundation for the development of new technologies in the field. [1]
It is produced by Varian, Inc. The software runs on SPARC machines with Solaris. It is composed of a command line interpreter window, an output window, and a status window. The successor of vnmr is called vnmrJ.
The first generation of NMR spectrometers used large Electromagnets weighing hundreds of kilograms or more. Slightly smaller permanent magnet systems were developed in the 1960s-70s at proton resonance frequencies of 60 and 90 MHz and were widely used for chemical analysis using continuous wave methods, but these permanent magnets still weighed hundreds of kilograms and could not be placed on ...
A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.
