Abstract:
A miniature mass spectrometer is disclosed comprising an atmospheric pressure ionisation source  701 , a first vacuum chamber having an atmospheric pressure sampling orifice or capillary, a second vacuum chamber located downstream of the first vacuum chamber and a third vacuum chamber located downstream of the second vacuum chamber. A first vacuum pump  707  is arranged and adapted to pump the first vacuum chamber, wherein the first vacuum pump  707  is arranged and adapted to maintain the first vacuum chamber at a pressure <10 mbar. A first RF ion guide  702  is located within the first vacuum chamber. An ion detector  705  is located in the third vacuum chamber. The ion path length from the atmospheric pressure sampling orifice or capillary to an ion detecting surface of the ion detector  705  is ≤400 mm. The mass spectrometer further comprises a split flow turbomolecular vacuum pump  706  comprising an intermediate or interstage port connected to the second vacuum chamber and a high vacuum (“HV”) port connected to the third vacuum chamber. The first vacuum pump  707  is also arranged and adapted to act as a backing vacuum pump to the split flow turbomolecular vacuum pump  706 . The first vacuum pump has a maximum pumping speed ≤10 m 3 /hr (2.78 L/s).

Claim (Index 6):
A miniature mass spectrometer as claimed in  claim 1 , further comprising an RF ion guide located in said second vacuum chamber.
