NIR spectroscopy

The Finder SD analyses heterogeneous samples, like meat, fish or cheese with minimal sample preparation efforts.

For its manufacturing processes, the food industry is dependent on monitoring ingredients such as fat, protein and water. Critical process parameters are recorded quickly and permanently using NIR spectrometers, examine the production process to the second for agricultural, food and meat samples. With the implementation of the Finder SD Rotator analyzer in the production process, better food can be produced more efficiently by the time-saving and non-destructive analysis of solid samples. Due to the Scanning Grating Technology that is used, the system is fast, robust and reliable. The creation of an ensured chemometric model that meets all technical and regulatory requirements is the most important factor for using NIR in the food industry.

The dust-proof and water-resistant Finder SD Rotator analyzer can be integrated at any workplace and for a variety of functions. The rotator for samples e.g. in a petri dish provides reproducible results. Due to the instrument‘s calibration standards the system constantly checks itself or is recalibrated. A fast and easy integration into user-specific applications is possible with HiperScan instrument drivers.
