Elemental analysis for dissemination of SI base unit of amount of substance, the mole. The OES instrument measures the content of a specific element in an unknown solution via comparison measurements with a primary reference solution of known mass content. PTB-made elemental solutions act as transfer standards for calibration of industrial applications.
