| | | Variable Wavelength Detector |
| The UltiMate® 3000 Variable Wavelength Detector (VWD) is the detector of choice for routine chromatography applications. It offers high sensitivity, low noise and drift and a wavelength range of 190–900 nm. The VWD is available in two variants. The standard version with a 10 Hz data rate is economically affordable for laboratories on a limited budget. The rapid separation version offers a data rate of up to 100 Hz to perfectly detect even the narrowest peaks. Both detectors are designed to meet the demanding requirements of today’s laboratories. - Low noise (typically < ±2.5 µAU) and drift (< 0.1 mAU/h) guarantee high sensitivity
- Linear range of up to 2.5 AU allows for the analysis of wide range of analyte concentrations [more]
- Easily adaptable detector allows use with HPLC applications from nano- through to semi-preparative HPLC
- Data collection rates of up to 100 Hz allow detection of even the sharpest peaks
- Predictive performance technology continually monitors system performance and warns of impending errors such as lamp failure.
