Diode Array Spectrometer For NIR Spectroscopy

Reliable and in keeping with the times
Spectroscopy in the near-infrared range (800 - 2500 nm) has developed into one of the most up-to-date analysis processes in recent years. And, it offers decisive advantages in comparison to classic absorption spectroscopy in the mid-infrared region:

Benefits

• Many substances and materials can be measured and quantitatively evaluated directly without the need of elaborate preparation of samples.
• Quartz materials suitable for NIR permit the use of probes coupled to waveguides over long distances
• The path length of optical cells or liquid probes can be severalmilimeters, thus providing clear constructive and application advantages

Chemometric evaluation processes are being used for qualitative and quantitative analyses. However, the increasing demands on quality and production controls, particularly in the area of foods, agriculture or synthetic materials require high levels of reliability, stability and reproducibility of measuring results –and thus the quality of the equipment used. On the basis of the proven MCS/MMS polychromator principle, Carl Zeiss has developed a diode array spectrometer system, which not only meets the requirements mentioned above, but also opens up new dimensions in the sensitivity of fiber optics. Measurements in the millisecond range, which until now were difficult or impossible to achieve even with considerably more expensive systems, become possible. In addition, the optimization of the waveguide technology also permits the low-loss connection of a wide range of different measuring heads and probes.
