Real-time process analysis with near-infrared spectrometry: Metrohm NIRSystems does it – very well.
The NIRS Analyzer Pro is a process analysis system based on high resolution diode array technology. It provides non-destructive analysis of granules, powders, slurries or opalescent substances directly in the process line without bypass – a true in-line system.
The NIRS Analyzer Pro is available with dedicated interfaces based on reflectance or transmittance technology, depending on which is best-suited for the respective application area. Measurements are done directly on the moving sample in the process stream. A high-intensity dual-lamp light source illuminates the sample directly or through an optical fiber. The light interacts with the sample and the reflected or transmitted light is measured by the diode array sensor. The backup lamp in the dual lamp system secures uptime and analytical accuracy is unchanged even after switching to a new lamp. The complete wavelength range is measured instantaneously, so that high-accuracy measurements are also possible on fast moving samples.
Calibrations are transferable between units ensuring easy expansion to other measurement points. Integration to process regulations systems can be done through an OPC interface.
