Abstract
An isotope dilution (ID) multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) method combined with an internal normalization approach for mass bias correction has been used to determine low-level sulfur (S) concentrations in a synthetically prepared mix using a 33S enriched spike material. Dilute (1 ug S/g) sulfur solutions were prepared from the NIST SRM 3154 (Sulfate Spectrometric Solution) to test the capability of this technique for measuring low-level sulfur concentrations. The concentration results for each solution were in excellent agreement with the gravimetric determination and deviate by less than 0.35%.
