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.

Dale A. Rosado, Jr., Tina S. Masterson, and Douglas S. MastersonJournal of Chemical Education2011 88 (2), 178-183Mass spectrometry (MS) has been gaining in popularity in recent years owing in large part to the development of soft-ionization techniques such as matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI). These soft-ionization ...
