Elemental Impurity Analysis in Pharmaceuticals

A method to identify the presence of heavy metals in pharmaceuticals was introduced in the United States Pharmacopoeia more than 100 years ago.

Daniel Morland of Butterworth Laboratories gives an overview of the current method limitations, considerations for the new methodology, and the risk-based assessments being carried out by manufacturers.
