Direct Current Glow Discharge Mass Spectrometry for Elemental Characterization of Polymers

摘要

A direct current glow discharge mass spectrometer has been used for a novel application, the sputtering and subsequent analysis of polymers. This was made possible by the application of a secondary cathode, a tantalum diaphragm placed in front of the nonconducting sample. Different types of polymers were measured (polytetra- fluoroethylene, polycarbonate, and poly(vinyl chloride)).
