Abstract :

The development of greener analytical techniques is a topic of great interest. There is an increasing need for new analytical methods that can be used for assuring safety and quality in food samples including adulterants, pesticide residues and unknown functional components. Ultra-performance convergence chromatography (UPC2) is considered a valuable tool helping to separate and determine compounds differing by subtle structural differences. UPC2 presents several advantages over high performance liquid chromatography (HPLC) and it takes less column equilibration time and consumes fewer organic reagents. UPC2 has recently been successfully used to separate and determine a lot of analytes including many pharmaceutical compounds. In this work, recent applications of UPC2 for the analysis of different compounds in food and biological samples were reviewed, in the hope of helping chromatography users to have a new look on the possibilities offered by this technique. Furthermore, a simple, highly sensitive and fast analytical method based on UPC2 with photodiode array detection (PDA) has been developed to quantify sulfonamides, monosaccharides and structural analogues of isoflavone isomers in food. Additionally, authentication technology based on fragment markers and high resolution mass spectrometry was developed for the quality assurance and pesticide residue compounds analysis in food.
