Adduct identification in MS-DIAL May 26, 2020, 07:38:37 AM I have been using MS Dial to process lipidomics data collected using a reverse phase UHPLC/TOF MS workflow. I have data sets collected using survey TOF MS and data dependent MS/MS and TOF MS with SWATH MS/MS methods. The data quality is good and I can observe several abundant lipid species can be observed I process the data manually using Sciex OS. I am still trying to optimize lipid identification using MS-DIAL, particularly for the SWATH data sets. One issue that is very vexing to me is that MS-DIAL does not identify ammoniated adducts of mono di and tri glycerides even though these are present in the data and checked in the processing set up (and I have selected the ammonium formate solvent option). Is there something trivial I am missing here? Are there other "tweaks" for processing this type of TOF MS data that would improve my lipid identification? Thanks in advance for any help.
