ABSTRACT:
A compressed gas sampling device is shown which includes a pressure reducing orifice to permit collection of a gas sample at a low pressure. A filter cartridge is connected between a flow meter and a pressurized source for analysis and gas is passed through the cartridge for a predetermined period of time. The cartridge may then be analyzed by a laboratory to determine contaminants which may be present in the source gas under analysis.
