Gas chromatography-mass spectrometry selected ion monitoring and gas chromatography-tandem mass spectrometry selected reaction monitoring analyses of mono-, di- and tri-unsaturated C < sub > 25 < /sub > highly branched isoprenoid alkene biomarkers in sea ice and sediment samples: A comparative study

CONCLUSIONS: Despite the intense migrations of HBI double bonds under electron ionization, the selected SRM transitions should be more suitable than SIM target ions for IP25 and HBI III quantification in complex hydrocarbon fractions of natural samples. However, the advantage is less evident for IPSO25 due to the presence of numerous regio-isomers.PMID:38356092 | DOI:10.1002/rcm.9704
