Time-of-flight mass spectrometer for analyzing dimensionally separated specimens on a specimen mount uses laser desorption with a pulsed laser and ion detectors with temporary high resolution for measuring ionic currents.

摘要

A beam splitter (2) splits a laser beam from a pulsed laser (1). Split laser beams are deflected onto specimens on a specimen mount (5) via two fixed mirrors (3,4). A lens/mirror (3) acting as a concave mirror focuses the laser beams. Nine specimens fit in a focusing grid and are ionized simultaneously by laser pulses. A focusing aperture system (6) draws off the ions of the nine specimens to form ion beams. An Independent claim is also included for a method for analyzing specimens in a time-of-flight mass spectrometer by using laser desorption with a pulsed laser.
