System for optimizing alignment of laser beam with selected points on samples in MALDI mass spectrometer

   
   

A mass spectrometry apparatus uses image processing of output signals of a camera in a mass spectrometer to provide feedback for directing the laser. The present invention provides for the determination of where samples have actually been deposited on a plate, and for the selection of different points for each sample, based on its structure, at which to aim a laser, during the cycle period of the mass spectrometer. Such feedback information increases the likelihood that the laser impinges samples and provides useful data.
