|Lipid isomer data import problem in scheduled MRM||stolltho||2020-07-02|
Hi sky team.
A similar problem was reported earlier (Small Molecule MRM extraction with isomers) but it seems the problem persists.
I've got a long list of lipids, some of which have the same transition pairs (774.6>184.1).
I already changed product ion m/z by 0.01 (774.6>184.10, 774.6>184.11) to circumvent the problem and it worked, but unfortunately the QQQ we are using is not acquiring identical peak profiles for this slight shift.
Hence I changed product ion m/z by 0.0010 (774.6>184.1000, 774.6>184.1010, 774.6>184.1009 etc.), but now I face the same import issue again, showing only one / the same sMRM window. I changed match tolerance to 0.0001, but then no chromatograms are shown after import.
