Abstract:
A miniature mass spectrometer is disclosed comprising an atmospheric pressure ionisation source and 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. An ion detector is located in the third vacuum chamber. A first RF ion guide is located within the first vacuum chamber and a second RF ion guide is located within the second vacuum chamber. The ion path length from the atmospheric pressure sampling orifice or capillary to an ion detecting surface of the ion detector is ≤400 mm. The mass spectrometer further comprises a tandem quadrupole mass analyser, a 3D ion trap mass analyser, a 2D or linear ion trap mass analyser, a Time of Flight mass analyser, a quadrupole-Time of Flight mass analyser or an electrostatic mass analyser arranged in the third vacuum chamber. The product of the pressure P 1  in the vicinity of the first RF ion guide and the length L 1  of the first RF ion guide is in the range 10-100 mbar-cm and the product of the pressure P 2  in the vicinity of the second RF ion guide and the length L 2  of the second RF ion guide is in the range 0.05-0.3 mbar-cm.

Claim (Index 24):
A mass spectrometer as claimed in  claim 21 , further comprising a fourth vacuum chamber located downstream of said third vacuum chamber.
