Compact, fully automated Prep Peak Collection System with advanced capabilities for unattended runs. Software uses proprietary real time algorithms to make peak detection and collection decisions so AutoPrep dynamically follows changes in retention time and loading in real time during the run. AutoPrep can collect the whole peak in a single collection channel. AutoPrep can be installed with most pumps and UV detectors. Personalized technical support from experienced chromatographers is included. System is excellent for any prep application, chiral or achiral.
