Abstract
Laser desorption/ionization tandem mass spectrometer instruments that include immediate post source collisional cooling are presented, as are analytical methods that employ such instruments to achieve increased sensitivity and ion yield. Also presented are laser desorption/ionization mass spectrometry methods that improve sensitivity and relative ion yield by combining affinity capture probes with matrices having low melting point energy absorbing molecules combined with alkali metal scavengers.
