Regioisomeric Analysis of Triacylglycerols Using Silver-ion Liquid Chromatography-Atmospheric Pressure Chemical Ionization Mass Spectrometry: Comparison of Five Different Mass Analyzers

Original language description

Silver-ion high-performance liquid chromatography (HPLC) coupled to atmospheric pressure chemical ionization mass spectrometry (APCI-MS) is used for the regioisomeric analysis of triacylglycerols (TGs). In total, 32 different regioisomeric doublets and 11 triplets are synthesized, separated by silver-ion HPLC using three serial coupled chromatographic columns giving a total length of 75 cm. The retention of TGs increases strongly with the double bond (DB) number and slightly for regioisomers having moreDBs in sn-1/3 positions. DB positional isomers (linolenic vs. gama-linolenic acids) are also separated and their reverse retention order in two different mobile phases is demonstrated. APCI mass spectra of all separated regioisomers are measured on fivedifferent mass spectrometers: single quadrupole LC/MSD, triple quadrupole API 3000, ion trap Esquire 3000, quadrupole time-of-flight micrOTOF-Q and LTQ Orbitrap XL.
