Method development for determination of trace amounts of silicon in hydrofluoric acid digests of biological samples and lung biopsy tissues by ICP-MS

A method was described for determination of trace levels of silicon by inductively coupled plasma mass spectrometry (ICP-MS) from hydrofluoric (HF) digests of biological samples. The volatility of silicon in HF digests was examined with synthetic solutions as well as soil and mine waste samples. A digestion scheme was optimized to achieve complete dissolution, avoid loss of volatile silicon specie
