The Variable Wavelength Detectors (VWD) are 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 20 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.
• Spectrum scanning functionality for analyte characterization

The VWD-3400RS is ideal for RSLC applications in single wavelength mode. For conventional LC applications, the detector allows data acquisition of up to 4 UV-Vis channels up to 5 Hz. Its wavelength scanning feature allows for analyte characterization.

Note: The VWD-3400RS is also available in a standard version (3100) with a data rate of up to 20 Hz for conventional methods.

Performance Examples

The UltiMate^® 3000 Intelligent LC series delivers improvements in HPLC performance while ensuring easy, reliable operation.The UltiMate 3000 series operates over a wide range of flow rates including preparative, analytic, micro, and nano/capillary scales, supporting applications such as discovery processes, quality control, and advanced research like proteomics.

Rapid Separation LC offers the highest flow-pressure range to meet your chromatographic goals whatever the may be. Developing separations in seconds rather than in minutes requires a system that provides excellent precision, speed, and performance.
