Abstract
A dual source mass spectrometer system (10) is operable in a first mode with an LC source [LC/MS] (12) and in a second mode with a GC source [GC/MS] (18). The GC source inputs into an ion source chamber (22) for delivering the ionized output from the GC source to the mass spectrometer. The GC source comprises a GC interface probe (30) which is retractably connected to the ion source chamber to take the GC interface probe from a retracted position in which it is disengaged from the mass spectrometer (whereby the system is operable in the first LC/MS mode) into a deployed position in which the GC interface probe is operatively connected to the ion source chamber of the mass spectrometer (whereby the system is operable in said second GC/MS mode).
Claims7
A method of operating a dual source mass spectrometer system in a first mode with an LC source [LC/MS] and in a second mode with a GC source [GC/MS], said GC source inputting into an ion source chamber for delivering the ionized output from the GC source to the mass spectrometer and wherein the GC source comprises a GC interface probe, the method comprising the steps of taking the GC interface probe from a retracted position in which it is disengaged from the ion source chamber, whereby the system is operable in said first LC/MS mode, into a deployed position in which the GC interface probe is operatively connected to the ion source chamber whereby the system is operable in said second GC/MS mode.
