To Process Sample of SSMS by Plasma of Cryogenic Hydrogen

A new method which uses plasma of cryogenic hydrogen for reducing isolate sam-ple to obtain conductivity in spark source mass spectrometry has been presented. Com-pared with the method mixed conductive powder it has the advantages that the sample isnot easely contaminated; the sensitivity is higher; the blank and the disturbed spectrumlines are decreased. To applicate and compare, some metal compounds have been red-uced and analyzed by SSMS. The optimum conditions have been selected in order to in-crease the rate of reducation.
