20120056084 | Apparatus Comprising an Ion Mobility Spectrometer - A mass spectrometer is disclosed comprising a first chamber and a second chamber. The second chamber is located downstream of the first chamber and an inter-chamber aperture is provided between the two chambers. An ion guide is located in the first chamber and an ion mobility spectrometer is located in the second chamber. Helium gas is provided to the first chamber. As ions are accelerated towards the ion mobility spectrometer from a relatively low pressure region they pass initially into the first chamber. The helium gas provided in the first chamber minimises ion fragmentation and ion discrimination effects as ions are accelerated into a relatively high pressure region. The ions are then transmitted by the ion guide and are subsequently transmitted to the ion mobility spectrometer located in the second chamber. | 03-08-2012 |
20130056629 | Mass Spectrometer - A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator and an ion guide arranged downstream of the ion mobility spectrometer or separator. A plurality of axial potential wells are created in the ion guide so that ions received from the ion mobility spectrometer or separator become confined in separate axial potential wells. The potential wells maintain the fidelity and/or composition of ions received from the ion mobility spectrometer or separator. The potential wells are translated along the length of the ion guide. | 03-07-2013 |
