Ultra performance liquid chromatography (UPLC) and high-performance liquid chromatography (HPLC) methods for determination of ascorbic acid (AA) and total AA (TAA) contents (as the sum of AA and dehydroascorbic acid (DHAA) after its reduction to AA) in fruit beverages and in pharmaceutical preparations were compared UPLC methods being simpler, faster and more economic methods of detection and quantification than HPLC, they represent an important alternative. UPLC is relatively new technique that ensures a decrease in run time and solvent consumption The term HPLC stands for High Performance Liquid Chromatography whereas the term UPLC stands for Ultra High Performance Liquid Chromatography. Therefore, the UPLC technique is a developed version of HPLC. Thus, the method of operation is the same for both techniques Step 9- Try the new method and adjust as required. Remember that column re-equilibration time has significantly increased compared to the UPLC method. After all of that you also must remember that you will lose resolution compared to the UPLC method and there may be reductions in sensitivity as well. 0 The term UPLC is a trademark of the Waters Corporation, but is sometimes used to refer to the more general technique of UHPLC. Detectors [ edit ] HPLC detectors fall into two main categories: universal or selective
