Introduction
Antimony occurs in multiple oxidation states, with Sb (III) and Sb (V) being the most common in natural environments. Since Sb (III) is generally more toxic than Sb (V) and speciation strongly influences its environmental fate, determining Sb’s chemical form is critical.
This study evaluated Sb (III) and Sb (V) in soil using a NexSAR™ HPLC-ICP-MS speciation-analysis-ready solution, comprising of a NexSAR inert HPLC system coupled to a NexION® 1100 ICP-MS. The combination of the HPLC pump flow and ICP-MS robust plasma deliver reliable, repeatable antimony speciation analyses with precision and consistency.
