    Impurity profiles of the raw gases were determined by various analyzers. In particular, sub pmol/mol levels of insulating gas in the matrix components (N2, O2, and Ar) were carefully measured, since the mole fraction of sf6 gas in the final step can be significantly biased by this trace amount of Sulfr hexafluoride in the raw gases of the matrix components.
