An ultra-performance convergence chromatography (UPC2) system coupled with Q-TOF-MS wassuccessfully applied to analyze triacyglycerols and diacylglycerols in cow milk. Total of fifty-six peaks were identified according to their elementary composition and secondary MS profiles. A better resolution and shorter analytical time were obtained by the present method in comparison to traditional chromatographic approaches combined with MS analyzer. Furthermore, UPC2 is environmentally friend analytical method with a drastic reduction of organic solvent usage. The UPC2-MS method could be an alternative approach besides LC-MS and GC-MS for triacyglycerols and diacylglycerols analysis.
