Laser spot control in maldi mass spectrometers

摘要: Mass spectrometers ionize samples by matrix-assisted laser desorption (MALDI). The are located on a moveable support plate, and irradiated pulsed laser. A fast positional control of spots is provided via system rotatable mirrors to relieve strain plate motion drive. If the spot position finely adjusted mirror follows movement sample intermittent can be replaced with continuous uniform motion. allows more ablation area. Galvo low inertia may used between beam generation Kepler telescope in housing also provide fully automatic adjustment MALDI time-of-flight mass spectrometers, at least if ion-optical elements equipped devices.
