title: High-resolution mass spectrometer for protein chemistry.
abstract: Matrix-assisted laser desorption/ionization is an accurate and sensitive method for measuring the molecular weights of peptides and proteins. Usually time-of-flight mass spectrometry is used to detect the laser-produced ions, but a new method called Fourier transform mass spectrometry offers greater sensitivity and much higher mass measurement accuracy.
