Elemental assay & impurity testing


We offer both targeted and screening trace and heavy metals analysis from ppm to ppt detection levels, depending on the technique used and the sample matrix. We can perform reliable and accurate analysis using ICP-OES and ICP-MS in accordance with ICH (ICH Q3D Elemental Impurities testing) and USP guidelines. We offer speciation analysis for As, Hg and other elements to ensure compliance and to help investigate process chemistries and reaction studies.
