Function Switching With Fast Asynchronous Acquisition |
摘要 |
A method of analysing 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. |

1. A method of analysing a sample comprising:
operating a mass spectrometer in a state or mode wherein first ions are analysed; switching a state or mode of said mass spectrometer so that second ions are analysed; acquiring a stream of mass spectral data wherein the acquisition of said mass spectral data is substantially asynchronous with and/or is not synchronised with the switching of said mass spectrometer between states or modes; and post-processing said stream of mass spectral data to produce: (i) mass spectral data relating to said first ions; and/or (ii) mass spectral data relating to said second ions. |
