| | | Photodiode Array Detector |
| The Photodiode Array Detector is the detector of choice for laboratories who need maximum flexibility. It can be used both for routine applications and applications such as method development and peak characterization. The 1 nm spectral resolution allows you to distinguish between closely related UV-VIS spectra and the comprehensive set of 3-D data tools in the Chromeleon® Chromatography Management Software makes it easy to process and report your data. - Low noise (<±10 µAU) and drift (<1 mAU/h) guarantee high sensitivity
- Stainless steel and PEEK™ flow cells provide maximum application flexibility.
- Data collection rates of up to 20 Hz allow detection and characterization of very sharp peaks
- Front access to prealigned cells and lamps simplifies routine maintenance and therefore minimizes instrument downtime
