Abstract
An interchangeable ion source for a spectrometer. The ion source includes an interface which mounts the ion source relative to a gas inlet of the spectrometer, a sample holder, a laser which produces a laser beam capable of ionizing the sample at ambient pressure, and an optical system. The ion source includes an equipment chassis which supports the interface, the sample holder, the laser and the optical system as a rigid unit such that the interface, the sample holder, the laser and the optical system remain in alignment upon attachment and detachment of the ion source from the spectrometer and an enclosure which embraces an atmosphere around components of the ion source. In addition, the ion source includes a circulator which circulates at least part of the atmosphere within the enclosure.
