Abstract : The patent discusses a hot atmosphere particulate sampler which is comprised of a heated sample box having a separator and filter, a sample probe, a remotely mounted condenser box and a heated vacuum tube for maintaining the temperature of a particulate sample during flow from the sample box to the condenser box. The heated vacuum is housed in an insulated, flexible umbilical cord, which also houses electrical, thermocouple and pitot tube leads. The temperature of the particulate sample is kept above dew-point during flow to a condenser box containing impinger bottles in a cooling ice and water bath. The system is operated by a control console which provides electrical power to the heaters and thermocouples and a vacuum to the impinger bottles of the condenser box. This invention was conceived to provide source emission tests with the capability of using Environmental Protection Agency (EPA) recommended particulate sampling trains in locations where the ambient temperatures are above 100F, such as found in ship testing and in some stationary testing.
