Abstract

The 2002 Chemistry Nobel Prize has mass spectrometrists everywhere celebrating. It recognizes work that put large proteins, 10,000 Da and up, into mass spectrometers. A description of Koichi Tanaka's experiments using laser desorption ionization and John B. Fenn's experiments using electrospray ionization is given along with a brief summary with references to previous researchers' work that Tanaka and Fenn were familiar with. The techniques Tanaka and Fenn used for their Prize-winning work—techniques that have revolutionized mass spectrometry—have yet to reach current chemistry textbooks, whatever their level.
