摘要: A method of analyzing a sample is disclosed comprising transmitting a first population of ions through a mass spectrometer and switching a state or mode of the mass spectrometer to produce a second population of ions. A sequential stream of mass spectra is acquired asynchronously with respect to switching the state or mode of the mass spectrometer. The stream of mass spectral data is then post-processed to produce mass spectra corresponding predominantly to the first and second population of ions.

摘要: A method of processing mass spectral data is disclosed comprising digitising a first signal output from an ion detector to produce a first digitised signal. A first set of peaks in the first digitised signal is detected and the arrival time To and peak area So of one or more peaks in the first set of peaks are determined thereby forming a first list of data pairs, each data pair comprising an arrival time value and a peak area value. One or more data pairs from the first list are then filtered out thereby forming a second reduced list, wherein a data pair is filtered out, attenuated or otherwise rejected from the first list if the peak area value of a data pair in the first list is determined to be less than a threshold peak area.

摘要: A mass spectrometer is disclosed comprising an Electron Transfer Dissociation device comprising an ion guide. A control system determines the degree of fragmentation and charge reduction of precursor ions within the ion guide and varies the speed at which ions are transmitted through the ion guide in order to optimise the fragmentation and charge reduction process.

摘要: A linear ion trap is disclosed wherein an asymmetric voltage waveform is applied to electrodes forming the ion trap which causes ions to become radially separated according to their differential ion mobility. An axial potential barrier is arranged at the exit of the ion trap such that ions having a first differential ion mobility and a first radial displacement are retained axially within the ion trap but ions having a second differential ion mobility and a second radial displacement are ejected axially from the ion trap.
