A new approach on the sample preparation of powdered dairy products

The analysis of pressed powdered dairy samples (whole and skimmed milk powder, milk protein, whey powder, cheese powder, infant formulas, etc.) by XRF spectrometry faces two major challenges: the inherent small-scale heterogeneity from many of those materials and the high fat content that may be present.


PANalytical has developed a novel approach for the reliable and consistent preparation of pressed powdered dairy samples. This approach minimizes heterogeneities, providing a truly representative sample and immobilizes the fat content allowing a unified pressing process, producing stable and consistent pressed pellets for a wide range of samples. This solution is valuable in a large number of industries including dairy product manufacturers, ingredient and food manufacturers, suppliers, analytical and research labs.
