ABSTRACT:
Provided is a portable system useful for sampling both particulate and vapor phase metallic impurities from gases that cannot by hydrolyzed. The system comprises valves for introducing and controlling the exhaust of the gas to be sampled from the system. The metallic impurities are entrapped on filters, with one filter being operated at ambient temperature to remove particulate metallic impurities, and with another filter being operated at a temperature below ambient in order to remove vapor phase metallic impurities. In operating the system, the system is first back-filled to create a pressure equilibrium across the valve which introduces the gas to the first filter means. The flow of gas through the entire sampling system is controlled by means of a critical orifice located between the filters and the valve for controlling exhaust of the gas from the system. The entire system is portable and allows for transport of the system with its filters to a laboratory in order to permit the most sophisticated and effective analysis of the metallic impurities in the filters under controlled laboratory conditions.
