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 ...
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 ...
Surface nuclear magnetic resonance (SNMR), also known as magnetic resonance Sounding (MRS), is a geophysical technique specially designed for hydrogeology.It is based on the principle of nuclear magnetic resonance (NMR) and measurements can be used to indirectly estimate the water content of saturated and unsaturated zones in the earth's subsurface.

Bruker 700 MHz nuclear magnetic resonance (NMR) spectrometer. Nuclear Magnetic Resonance (NMR) basic principles. Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are disturbed by a weak oscillating magnetic field (in the near field [1]) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic ...
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]
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 ...
