Abstract

A thermal ionisation mass spectrometric procedure was developed for the measurement of platinum. Single and double filament techniques were investigated. Negative Pt ions were produced in the source of a thermionic quadrupole mass spectrometer equipped with a secondary electron multiplier operated in ion counting mode. A high purity platinum aqueous sample solution of natural isotopic composition was used as sample on a rhenium filament. This method allows the natural amount ratio of the major isotopes (194)Pt to (195)Pt to be measured with a repeatability of 0.3%.
