This Shimadzu 20AD Gradient LC System with PDA Detector comes expertly refurbished from GenTech Scientific and is currently used in a wide variety of fields. Higher reliability in analysis data and higher efficiency in total analysis workflow are required for faster development of new drugs, for better food safety, and for meeting higher standards in environmental regulations. Many analysis techniques use LC/MS, which requires a front-end HPLC system to provide solvent delivery performance in the micro to semi-micro range and injectors with low sample carryover. Prominence is a network-ready LC system that meets the demands of today’s advanced users.
