    NIR Technology

    NIR (Near Infrared) reflectance method yields accurate representative analyses for solid or semi-solid dairy products. Plus, analysis can be easily replicated.

    Versatility and stability across the full spectral range from 400 to 2500 nm.

“We want to know that if the certificate on a delivery states 80% protein that it is right.”

Glanbia Nutritionals, UK explain how discriminant analysis adds a valuable layer of security to their production process.
