Inorganic Elemental Analysis
Whether metals, salts, liquids or organic samples, all types of substances and materials are examined for element contents or traces in inorganic elemental analysis using modern analytical instruments.
For example, the determination of heavy metals in pharmaceuticals, intermediates and raw materials according to ICH Q3D is an important field of application for elemental analysis. Semi-quantitative screening analyses from a combination of ICP-MS and ICP-OES often provide a valuable data basis for a subsequent risk analysis regarding heavy metal contents.
Experienced chemists search together with the customer for a meaningful and cost-optimized analysis method for his samples. Great attention is also paid to the correct digestion procedure (keyword: volatile elements).
