The Thermo Scientific™ Dionex™ UltiMate™ 3000 VWD Rapid Separation Variable Wavelength Detectors are the detectors of choice for routine chromatography applications. They offer high sensitivity, low noise and drift, and a wavelength range of 190–900 nm. The VWD is available in two variants. The standard version (VWD-3100), with a 100 Hz data rate, is economically affordable for laboratories on a limited budget. The rapid separation version (VWD-3400RS) offers a data rate of up to 200 Hz to perfectly detect even the narrowest peaks. Both detectors are designed to meet the demanding requirements of today’s laboratories.
