In 1983, he graduated from Tohoku University with a bachelor's degree in engineering. As of 2008, he is the only person without a post-bachelor's degree to have won a Nobel Prize in a scientific field. After graduation, he joined Shimadzu Corporation, where he engaged in the development of mass spectrometers.
For mass spectrometry analyses of a macromolecule, such as a protein, the analyte must be ionized and vaporized by laser irradiation.
The problem is that the direct irradiation of an intense laser pulse on a macromolecule causes cleavage of the analyte into tiny fragments and the loss of its structure. In February 1985, Tanaka found that by using a
