Abstract: Embodiments include systems and methods for collection and identification of particulates in the air. In one embodiment, two different path ways are provided from a single adjustable inlet: one for collection and one for detection. A removable insert positionable within a collection tube enables a user to switch between the collection mode and the detection mode. This embodiment captures both the physical mechanisms of switching the air flow paths as well as sequencing of controls and valves and regulation or changing the air flow rate in the different modes of operation. This and other embodiments are disclosed herein.
