Here, you set the parameters used to generate Extracted Ion Chromatograms (EICs).
Single m/z expansion chromatograms | This parameter is used for creating EICs from a Total Ion Chromatogram (TIC) or from an MS spectrum. It is only used for single m/z values, not for mass ranges! |
EIC extraction retention time window for target compounds |
During quantification or MS sample purity calculation, EICs for each compound are automatically extracted. With the extraction retention time window, you limit the time range around a compound's retention time for which these EICs are extracted. You can thus make sure that the correct peaks are used. If you provide both absolute and relative time ranges, a sum of both will be used (same principle as for the peak identification window). |
