Ie. Vasilyeva et al., Selection of internal standard for determination of boron and phosphorus by ICP-MS in silicon photovoltaic materials, J ANAL ATOM, 14(9), 1999, pp. 1519-1521
A single-chamber autoclave with a heating plate was used for the acid disso
lution of quartz and metallic silicon. Analysis was performed by ICP-MS. Co
mparison of Li-6, Li-7, In-115, Cl-35 and Cl-37+(ArH)-Ar-36-H-1 was carried
out for selecting the best internal standard taking into account instrumen
tal drift. The selection criteria are discussed. Cl-35 was selected as the
internal standard.
