The Variable Wavelength Detectors (VWD) 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.

• 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 a 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 200 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 PCM-3000 pH and Conductivity Monitor is an upgrade for accurate on-line pH and conductivity monitoring with the VWD-3000 Series. A typical application area of this unit is monitoring the gradient formation in salt- or pH-gradient-based ion-exchange chromatography (IEC) in biopharmaceutical analysis.

The VWD-3400RS is ideal for any UHPLC application in single wavelength mode. For conventional LC applications, the detector allows data acquisition of up to 4 UV-vis channels up to 5 Hz. The VWD-3100 is ideal for use with
UltiMate^™ 3000 analytical systems. Both detector variants support wavelength scanning  for method development or analyte characterization. 

Performance Examples

UltiMate^® 3000 HPLC systems deliver improvements in HPLC performance while ensuring easy, reliable operation.The UltiMate 3000 series operates over a wide range of flow rates, including preparative, analytical, 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.
