Shimadzu Corporation is a Japanese company which manufactures precision instruments, measuring instruments and medical equipment. Central Headquarters are in Kyoto, Japan.
It was founded in 1875 by Genzo Shimadzu. The first instruments developed were X-ray devices, spectrum cameras, gas chromatographs and electron microscopes.
One of the major milestones of the company was the Nobel Prize in Chemistry won in 2002 by Koichi Tanaka, a Shimadzu employee. The prize was awarded for developing a method of mass spectrometric analysis of biological macromolecules.
Shimadzu acquired the british company Kratos Analytical Ltd., which is now responsible for design, construction and sales of Shimadzu mass spectrometres.
