Abstract:
1. A system for measuring at least one metal analyte from a halosilane source, comprising: (a) a halosilane source comprising at least one halosilane having a formula Si (b) at least one reaction system coupled to said halosilane source, wherein a first sample comprising the halosilane is collected from the halosilane source, wherein the first sample and an aqueous hydrofluoric acid solution are contacted in the reaction system to produce a liquid reaction mixture, and the reaction system comprises: (c) an evaporator, wherein the evaporator is used to evaporate liquid from the liquid reaction mixture to produce a near-dry residue, wherein the near-dry residue is mixed with a take-up liquid to produce a second sample, and (d) a metal analyte detector, wherein the metal analyte detector is used to analyze the second sample for the presence of a detectable amount of at least one metal analyte.
