Abstract
A method of mass spectrometry comprising the steps of: providing a library of background ion data including m/z data for multiple background ions in respect of different chromatographic conditions including a change of solvent composition from aqueous () to organic (), chromatographically separating a sample containing analyte components, wherein the chromatographic separation is performed under a chromatographic condition in respect of which background ion data is provided in the library, analysing the sample to obtain sample data comprising m/z values for the sample components as a function of retention time (RT), and calculating one or more error values including ppm error as a function of retention time based on a comparison between background ions identified in the sample data and the library of background ion data. Outliers (), corrupted measurements and inconsistent measurements at specific retention times are rejected.
