Various embodiments of the present disclosure provide a sampling device, system, and method. The sampling device includes a sample inlet nozzle fluidly coupled to a dilution body. A carrier fluid delivery conduit is also fluidly coupled to the dilution body. In one implementation, the carrier fluid delivery conduit is coupled to a source of heated carrier fluid. Carrier fluid is delivered around a perforated portion of the sample inlet nozzle, in one configuration. In some cases, the sampling device includes a mixing device configured to produce laminar flow of carrier fluid about a fluid sample. In other cases, the mixing device produces turbulent flow of carrier fluid and fluid sample. Systems including the sampling device include, in some implementations, a sample separator, such as an inertial droplet separator. In further implementations, systems including the sampling device further include an atmospheric dispersion simulator.

The present disclosure provides methods, systems, and apparatus for continuously monitoring particulates emitted from an emissions source. In a particular embodiment of a disclosed system, the system includes a sample inlet and diluent inlet. The system further includes a mixing chamber in communication with the sample inlet and the diluent inlet. An aerosol sample from the emissions source and diluent from the diluent inlet, received through the respective sample and diluent inlets, are mixed in the mixing chamber. The system includes an ambient dispersion simulator in communication with the mixing chamber. A diluted aerosol sample passes from the mixing chamber to the ambient dispersion simulator, where it is conditioned to produce a conditioned aerosol sample. The conditioned aerosol sample enters a continuous particle detector. The continuous particle detector is configured to make multiple distinct measurements without intervention by a user.
