Sophisticated complete HPLC systems offer an easy and improved liquid chromatography method for separating mixture compounds essential for further quantification or identification analyses. Instead of the sample traveling through the column by gravitational means, this equipment utilizes a forced air pressure push to achieve faster results. Pumps maintain a consistent flow rate while ultra-sensitive detectors assist with accurate retention times. For better separations, the complete HPLC systems allow pre-packed stationary phase materials with smaller particle sizes.
