Abstract :

The development of greener analytical techniques is a topic of great interest. There is an increasing need for new analytical methods that can handle a large number of analytes in food and biological samples. 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); it takes less column equilibration time and consumes less 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 photo-diode array detection (PDA) has been developed to quantify 15 sulfonamides and their N4-acetylation metabolites in serum. Variables affecting the UPC2 were optimized to get a better separation. We provide a discussion of stationary phase, modifiers and additives, column temperature, flow rate, and automatic back pressure regulator (ABPR) backpressure for UPC2 analysis and detection sensitivity. The performance of the developed method was also evaluated.
