DS2500 Analyzer –

why you should prefer

a dispersive system

Quantification of analytes in the lower ppm range is a challenge for near-infrared spectrometers. Dispersive systems with their unmatched signal-to-noise ratio are the preferred solution for those tasks. The D(ispersive)S(ystem)2500 Analyzer from Metrohm is an ideal tool for such complex tasks, for solid as well as liquid samples.

Extended wavelength range for measurements in the near-infrared and the visible range The DS2500 Analyzer is designed for typical half widths of NIR signals (up to 30 nm) and offers a resolution of 8.75 nm over a wavelength range of high humidity or dust load, system robustness can 400–2500 nm. Hence, the DS2500 Analyzer covers make all the difference.
