BELL CAP AEROSOL ADAPTOR

摘要

A method of testing an air sample and/or testing equipment may comprise introducing aerosolized sample particles into an air flow to create sample air upstream from an air quality sampling device. The method may include introducing the sample air to an offset sample inlet of a bell cap inlet adaptor coupled to a sample tube. The method may include merging at least a portion of the introduced sample air with axially flowing air with little to no turbulence based on the geometry of the bell cap inlet adaptor and/or a containment cavity. The method may include introducing at least a portion of the sample air into the sample tube. Next, a test of at least one of the quality of the sample air and/or the functionality of the bell cap inlet may be performed.

1. A bell cap inlet adaptor comprising:
a sample inlet in fluid communication with a containment cavity; wherein the containment cavity is in fluid communication with an inlet to a sample tube, wherein air drawn through the sample tube imparts an axial cyclonic flow of air within the containment cavity, and wherein the sample tube is offset from concentric from the containment cavity.
