Near-infrared spectroscopy is an optical measurement method for non-destructive determination of chemical and physical properties in real time.
Sensor directly in the process stream — no sampling, continuous real-time measurement.
Automatic sampling via bypass loop — short analysis times, close to the process.
Sample analysed next to the line — flexible location, manual or automatic sampling.
Laboratory analysis — highest accuracy, longer analysis times, spatially separated from the process.
