Abstract

Thermal ionisation mass spectrometry of silicon has been developed, enabling high accuracy assay of Si by isotope dilution mass spectrometry (ID-MS). The method works with silicon in the form of sodium silicate and uses barium hydroxide to enhance ionisation. In the process a 29Si spike reference material was established. The new method was tested on water samples doped with 15 ppb of silicon and it is shown that ppb traces of silicon in water can be assayed to better than 10% accuracy (total uncertainty).
