Abstract
Various embodiments and implementations herein are directed to an aerosol and vapor sampling device that has a nozzle capable of focusing/concentrating the sampled particles by accelerating them in a narrow jet and driving the particles into an impaction well containing a collection substrate. The aerosolized particles, aerosolized droplets, and chemical vapors are retained by using a porous collection substrate, having substantial depth and mounted on a porous backing, such as a screen. This configuration allows a minor air flow through the collection substrate. This minor flow allows a well impactor to retain intercepted aerosolized particles. It also improves the inlet's ability to collect and retain chemical vapors or liquid aerosol droplets that are partially filtered and captured in the substrate's matrix.
