HPLC systems seem to be getting better with age. Recently, within the last 10 years there has been a big focus on innovation and improvement of these commonly used instruments within modern laboratories. This focus has lead to the development of the Ultra High Performance Liquid Chromatography (UHPLC) Systems that offer greater performance of mass detectors, improved column technologies, and faster result times.
