HPLC and UHPLC Variable Wavelength Detectors

Sensitive, accurate UV-Vis detection

Ensure high sensitivity and accuracy during UV-Vis detection of your analytes with our variable wavelength detectors (VWDs) for HPLC. Thermo Scientific Variable Wavelength Detectors offer several advantages, including excellent noise, drift, and linearity performance to support a wide operating range and trace compound detection. These absorbance detectors are easy to operate and streamline sample analysis by covering both the UV and Vis ranges of light.


High-performance UV-Vis detection

Thermo Scientific Vanquish Variable Wavelength Detectors yield robust and high-performance UV-Vis absorption detection. With up to 250 Hz, the detectors keep pace with any current and future HPLC and UHPLC detection challenges. A wide flow cell portfolio is available to match your application requirements, while the design, automated performance and wellness monitoring, and a wide range of usability features give you full confidence in your analytical results. Detect trace analytes next to main compounds with a large linearity range of up to 2.5 AU, as well as a wide wavelength range. Simplify method development with up to four absorption channels and spectral scans. Minimize baseline drift and noise with active temperature control of optics for the detection of even the smallest quantities of trace compounds. Maximize data collection rates up to 250 Hz for today’s and tomorrow’s fastest UHPLC applications.
