Metrohm - NIRS XDS - Interactance Optiprobe Analyzer

The NIRS XDS Interactance OptiProbe Analyzer enables the simple and reliable monitoring of chemical reactions in technical centers and pilot plants. The method development and the scale-up of production processes are areas of application in which the NIRS XDS Interactance OptiProbe Analyzer supplies precise results regarding the identity and quality of a wide variety of samples. Whereas solids, strongly scattering liquids and slurries are measured with the reflection probe, the immersion probe is used to analyze aqueous products, clear liquids and solvents. The probe is connected to the analyzer through an optical fiber to enable secure measurements even under rough and/or dangerous conditions in the processing environment.
