The main advantages of near-infrared spectroscopy compared with other techniques are that there is no need for sample preparation and results for different parameters are available very fast. The new NIRS DS 2500 from Metrohm provides superior sensitivity for analysis down to concentrations in the lower ppm-range. It covers both the near-infrared range and the visible range, which means that, unlike FT systems, the NIRS DS2500 Liquid Analyzer can also detect color changes of the sample, e.g., caused by aging.
The DS2500 with its IP65 certified housing and only one rotating optical element is a highly robust solution providing excellent protection against environmental influences even in high vibration environments. The rotating high-precision grating used to disperse light guarantees fast data acquisition so that results are obtained within 30 seconds. With the DS2500 Liquid Analyzer, users can choose from a variety of cuvettes, flow cells and disposable vials, giving them the flexibility to adapt to the respective sample. Intelligent sample holders in combination with SOPs help prevent errors in routine operation that could otherwise result from accidentally selecting the wrong sample containers.
