Ultra-high Performance Supercritical Fluid Chromatography Combined with Quadrupole Time-of-Flight Mass Spectrometry for the Characterization of Pentaerythritol Fatty Acid Esters.

CONCLUSIONS: A UHPSFC/QTof-MS method was successfully employed for the separation of pentaerythritol fatty acid esters. Exact masses and product ion information were given by high resolution mass spectrometry. The composition of the fatty acids was effectively deduced by characteristic ions and their relative abundances. This method is an effective means for the quality control and process optimization of this type of product, serving as a positive reference for further study on pentaerythritol fatty acid esters.
