    摘要: An ion source for a mass spectrometer is disclosed comprising a lens and mirror arrangement which focuses a laser beam onto the upper surface of a target substrate. The lens has an effective focal length ≦300 mm. The laser beam is directed onto the target substrate at an angle θ with respect to the perpendicular to the target substrate, wherein θ≦3°. One or more ion guides receive ions released from the target substrate and onwardly transmit the ions along an ion path which substantially bypasses the lens and mirror.

    摘要: A mass spectrometer is disclosed comprising two vacuum chambers maintained at different pressures. The two vacuum chambers are interconnected by a differential pumping aperture. The effective area of the opening between the two vacuum chambers may be varied by rotating a disk having an aperture in front of the differential pumping aperture so as to vary the gas flow rate through the opening and between the two chambers.

    摘要: A mass spectrometer is disclosed comprising an ion trap and a fragmentation device. Ions are fragmented in the ion trap to form first generation fragment ions. The ion trap has a relatively high mass cut-off. The first generation fragment ions are then transferred to a fragmentation device which is arranged to have a substantially lower low mass cut-off. The first generation fragment ions are fragmented within the fragmentation device any may optionally be stored in an ion accumulation region prior to being passed to a mass analyser for subsequent mass analysis.
