- Abstract
Due to chloride polyatomic interferences, hydrochloric acid is not recommended for preparation of samples analysed by ICP-MS and separate digestion procedures are used for ICP-MS and ICP-AES. Here we demonstrate that a single digestion procedure using a mixture of HNO3 and HCl can be used for ICP-AES and dynamic reaction cell (DRC)-ICP-MS. Hotplate, block digester and microwave digestion were investigated. For a quantitative recovery of 26 elements including Ag, Sb and Ti from waters, soils and sediments, the final concentration of 10% (v/v) HCl in the digest is required regardless of the digestion techniques. The method detection limits of 0.3–1.2 μg/L were obtained for chloride-interfering elements As, V, Cr and Se by DRC-ICP-MS using ammonia and oxygen as the DRC gas.
