Giving excellent signal-to-noise performance and a wide dynamic range, the Thermo Scientific Diode Array Detectors and Multiple Wavelength Detectors employ a variety of technologies to allow you the flexibility to choose the right solution for your application.

Thermo Scientific Vanquish Diode Array Detectors (DADs) and Multiple Wavelength Detectors (MWDs) are designed for the highest performance, reliability and flexibility. Detect trace analytes next to main compounds due to a wide dynamic range and a low limit of detection. A wide portfolio of flow cells allows you to find the perfect match to your application needs.

  • Dispersion-optimized, robust Vanquish Flex and Core flow cells are ideally suited for any setup including LC-MS applications and other hyphenated techniques.
  • If the highest performance is in demand, the Thermo Scientific LightPipe detection technology delivers outstanding sensitivity with low-dispersion 10 mm and 60 mm flow cells. Achieve the best signal-to-noise performance through the combination of the lowest baseline noise, minimum peak dispersion, and a very long light path.
  • Versatile and ultrafast separations with a wide spectral range, programmable optical slit widths, low baseline drift, fast data acquisition, up to 10 signal channels, and one 3D field.
