Abstract
A non-conductive isolator for supporting a sample to be analyzed by radio frequency energy induced glow discharge techniques has a conductive ring for coupling a source of radio frequency energy to the same surface of a sample which is in direct contact with the induced glow discharge. An adapter kit for converting a direct current glow discharge analysis apparatus to a radio frequency energy induced flow discharge is also disclosed as well as the method of analyzing non-conductive and sample conductive using a source of RF energy coupled to the same sample surface being analyzed.
