Standards 

Our collection of international major and minor element standards include a wide range of natural and synthetic minerals and glasses, which enables us to solve a considerable range of analytical problems. An increasing emphasis is put on trace element analysis covering concentration ranges down to the hundred ppm (parts per million) range. Trace element standards include magmatic volatiles (F, Cl, S), a wide range of metals, and rare earth elements.
