Novel approaches to analysis of 3-chloropropane-1,2-diol esters in vegetable oils
Original language description
A sensitive and accurate method utilizing ultra-high performance liquid chromatography (U-HPLC) coupled to high resolution mass spectrometry based on orbitrap technology (orbitrapMS) for the analysis of nine 3-MCPD diesters in vegetable oils was developed. To remove the interfering triacylglycerols (TAGs) that induce strong matrix effects, a clean-up step on silica gel column was used. The quantitative analysis was performed with the use of deuterium-labelled internal standards. The lowest calibration levels estimated for the respective analytes ranged from 2 to 5 ?g kg-1. Good recovery values (89-120%) and repeatability (RSD 5-9%) were obtained at spiking levels of 2 and 10 mg kg-1. As an alternative, a novel ambient desorption ionization technique, direct analysis in real time (DART), hyphenated with orbitrapMS, was employed for no separation, high-throughput, semi-quantitative screening of 3-MCPD diesters in samples obtained by chromatographic fractionation. Additionally, the levels
