ABSTRACT:
The invention provides a mass spectrometer having improved mass resolution, accuracy, sensitivity, reduced complexity, lower cost, and greater ease of use. The mass spectrometer provided comprises a first electrode and a second electrode, in a nested configuration to create a two-stage acceleration region that accelerates ions across a minimized acceleration region, resulting in decreased metastable decay and improved mass accuracy and resolution. The mass spectrometer also comprises a n alignment system to align the ion optics with the laser beam used for desorption/ionization. The mass spectrometer further comprises electrical circuits for delivering high voltage pulses for pulsed delayed ion extraction.
