A single-chamber autoclave with a heating plate was used for the acid dissolution of quartz and metallic silicon. Analysis was performed by ICP-MS. Comparison of 6Li, 7Li, 115In, 35Cl and 37Cl+36Ar1H was carried out for selecting the best internal standard taking into account instrumental drift. The selection criteria are discussed. 35Cl was selected as the internal standard.
