  • Particle sampling system for gas supply system
    Patent number: 5537879
    Abstract: A particle sampling system which includes a flow restrictor positioned in a conduit between a vent and an analyzer probe and restricts flow in the conduit to maintain an overpressure of sample gas at the counter probe which, in turn, forces the gas sample into the particle analyzer. The system further includes a reservoir for holding a working fluid usable with a particle analyzer and a pressurized gas source which is used to pressurize the reservoir to enable supply of the working fluid against the pressure of the gas analysis sample and to provide a purge gas for the analyzer.
