| The Rapid Separation Diode Array Detector (DAD-3000RS) is one of the powerful detection options for the UltiMate® 3000 Rapid Separation LC System and can collect data at a rate of up to 100 Hz, with full wavelength spectra acquisition. The narrowest peak can be detected reliably—even 10 peaks in 10 seconds are no problem! Achieve a new level of flexibility for routine operation or for method development with up to eight channels of single-wavelength data acquisition together with 3D data. The DAD-3000RS features noise and drift performance specifications previously only available in forward-optic detectors, a 1024 element diode array, and 1 nm resolution. This resolution allows you to distinguish between closely related UV-VIS spectra, and the comprehensive set of 3D data tools in the Chromeleon® Chromatography Management Software makes it easy to process and report your data. Data collection rates of up to 100 Hz allow detection and characterization of even the sharpest peaks [ more] Low noise (< ±8 µAU) and drift (<1 mAU/h) guarantee high sensitivity Front access to pre-aligned cells and lamps simplifies routine maintenance and therefore minimizes instrument downtime. Both the lamps and the flow cell feature an ID chip for tracking of all relevant parameters. The flow cell range covers micro- and analytical flow rate applications. Cells are also available in a biocompatible design.
The Diode Array Detector is also available in a standard version with up to 20 Hz data collection rate (DAD-3000). All other specifications are as for the rapid separation version. This detector perfectly supports conventional HPLC applications. Performance Examples
