EDXRF for Pharmaceutical Material Elemental Analysis

One of the most common safety related analytical tests is the quantification of inorganic impurities within pharmaceutical products. Many active pharmaceutical ingredients (APIs) may contain residual metal catalysts. Since there are also many potential sources of contamination, it is valuable to measure raw materials, intermediates and final products. This study demonstrates that the X-ray Fluorescence technique is capable of performing elemental analysis of pharmaceutical materials with high sensitivity, precision and accuracy.
