A die for pelletizing samples for X‐ray fluorescence analysis

Abstract

Abstract The preparation of pellets of powdered geological samples is a critical step in X‐ray fluorescence analysis. A special die has been designed to produce smooth surfaces on extremely durable pellets and to provide a protective, hard outer ring and backing. The outer ring minimises the deterioration of the edge that has in the past limited the usable life of the pellet. Repetitive preparations have shown reproducibility and homogeneity to be within normal counting statistics.
