The Use of Molecular Sieves in Stable Isotope - ScienceDirect

Jan 01, 2004 · The SiF4 was extracted from the samples using the BrF5 method of Clayton Mayeda (1963). Purification of the SiF4, however, was necessary because contaminants such as Sulfr hexafluoride, SO2F2 and CF4 were also created. One of the purification methods that Molini-Velsko (1983) examined involved using a molecular sieve col- umn in a gas chromatograph.Get price
