Collect full spectral data for postacquisition analysis with the Dionex UltiMate 3000 Photodiode Array Detector. It supports both HPLC and UHPLC applications with eight channels of single-wavelength data acquisition, a 1024-element diode array, and the excellent noise and drift performance of a forward-optic detector. Diode array detection allows full spectrum acquisition at speeds up to 200Hz. Comprehensive three-dimensional data tools in Dionex Chromeleon Chromatography Data System software makes it easy to process and report your results.
