Abstract:
1. An apparatus for aerosol collection and fluid analysis, comprising: a rotary motor including a stage configured for rotation; an aerosol-collection disk including at least one interior inlet, at least one peripheral outlet and a passage coupling the interior inlet with the peripheral outlet, and a particle collector opposite the peripheral outlet, wherein the collection disk is configured for mounting on the stage of the rotary motor for rotation thereon; a fluid-analysis disk configured for mounting on the stage of the rotary motor for rotation thereon, the fluid-analysis disk comprising at least one fluid in each of a first reservoir and a second reservoir on or in the fluid-analysis disk and offset from a central axis of the fluid-analysis disk, wherein each reservoir has an outlet and a stopper in the outlet of each reservoir to seal the reservoirs, wherein selection between release of fluids from the first and second reservoirs is determined by the rate of rotation of the fluid-analysis disk or by acceleration in the rate of rotation of the fluid-analysis disk, wherein the fluid-analysis disk is configured to release the fluid from the first reservoir when the fluid-analysis disk reaches a first rotation or rotation-acceleration rate, wherein the fluid-analysis disk is configured to release the fluid from the second reservoir when the fluid-analysis disk reaches a second rotation or rotation-acceleration rate distinct from the first rotation or rotation-acceleration rate, and wherein the fluid-analysis disk is characterized by at least one of the following:
