You might want to check out the following paper: "Benefits of DRC-ICP-MS to Determine Ultra-trace Contamination Levels in High Purity Sulfuric and Phosphoric Acid" by Kawabata, Kishi and Thomas in Spectroscopy 18 (1), 16-31, (2003). Although it uses a dynamic reaction cell to reduce many sulfur and phosphorus-based polyatomic interferences, it also discusses the sample preparation steps and
details of the sample introduction system used. You will find the paper at the following web address:
I hope it helps.
