    Abstract: An ion source is disclosed wherein a sample is introduced into the sample chamber (1) of the ion source in the gas phase via a sample introduction capillary tube (2). The sample is directed onto a heated surface (6) coated with an oxidising reagent such as copper oxide. Carbon in the sample is oxidised to form carbon dioxide. The resulting carbon dioxide molecules are then ionised by electron impact ionisation with an electron beam (3) and the resulting ions are passed to a mass analyser for mass analysis.

    Abstract: A method of mass spectrometry is disclosed wherein an Electron Capture Dissociation, Electron Transfer Dissociation or Surface Induced Dissociation fragmentation device is repeatedly switched between a high fragmentation or reaction mode and a low fragmentation or reaction mode. Parent ions from a first sample are passed through the device and parent ion mass spectra and fragmentation ion mass spectra are obtained. Parent ions from a second sample are then passed through the device and a second set of parent ion mass spectra and fragmentation ion mass spectra are obtained. The mass spectra are then compared and if either certain parent ions or certain fragmentation ions in the two samples are expressed differently then further analysis is performed to seek to identify the ions which are expressed differently in the two different samples.

    Abstract: A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator (6) arranged upstream of a collision or fragmentation cell (8). Ions are separated according to their ion mobility within the ion mobility spectrometer or separator (6). The kinetic energy of the ions exiting the ion mobility spectrometer or separator (6) is increased substantially linearly with time in order to optimise the fragmentation energy of ions as they enter the collision or fragmentation cell (8). During the time that the potential of the ion mobility spectrometer or separator (6) is being varied, the potential of ion-optical components upstream of the ion mobility spectrometer or separator (6) such as an ion source (1), ion guide (2), quadrupole mass filter (3), optional second collision or fragmentation cell (4) and an ion trapping device (5) are kept constant.
