Analysis of high purity antimony by glow discharge quadrupole mass spectrometry

Characterization of a high-purity antimony sample for its trace and ultratr ace level impurities has been carried out using GD-QMS. Relative sensitivit y factor (RSF) values generated from the analysis of NIST standard referenc e materials (Low Alloy Steel SRM 1761 and SRM 1762) were used to compute th e concentrations. These RSF values were validated through the analysis of N IST Low Alloy Steel SRM 1766. The impurity levels determined through GD-QMS were cross-validated with other solution-based techniques, namely ICP-QMS, ICP-OES, and GFAAS. Good agreement was observed for many elements where in terferences were not noted.
