Method of Optimising Spectral Data |
摘要 |
A method of mass spectrometry or ion mobility spectrometry is disclosed. The method comprises: providing a plurality of species of ions; analysing the ions during a plurality of sequential acquisition periods so as to obtain spectral data relating to the ions; varying the value of an operational parameter of the spectrometer such that it has different values during the different acquisition periods, wherein the spectral data obtained for a given ion varies depending on the value of the operational parameter; storing the spectral data obtained during the different acquisition periods separately; selecting a target ion; and then interrogating the spectral data so as to identify a set of first acquisition periods that include data corresponding to said target ion. Selecting spectral data from only a subset of the first acquisition periods allows the selection of the optimal spectral data for the target ion, whilst discarding less optimal data. |

1. A method of mass spectrometry or ion mobility spectrometry comprising:
providing a plurality of species of ions; analysing the ions during a plurality of sequential acquisition periods so as to obtain spectral data relating to the ions; varying the value of an operational parameter of the spectrometer such that it has different values during the different acquisition periods, wherein the spectral data obtained for a given ion varies depending on the value of the operational parameter; storing the spectral data obtained during the different acquisition periods separately; selecting or identifying a target ion; and then interrogating the spectral data so as to identify a set of first acquisition periods that include data corresponding to said target ion; and selecting spectral data obtained in only a subset of said first acquisition periods so as to obtain spectral data that is optimised for said target ion. |
