ABSTRACT:
An air sampling device and method to produce simulated samples of airborne substances obtained from institutional and industrial facilities. The device features 1) an environment container, 2) an ejector for introducing a contaminant into the container environment, 3) a sample collection holder to hold a filter, 4) a pump to withdraw the container environment and contaminant out of the container in a fashion that allows collection of the contaminant on the filter, and 5) a container inlet to allow replacement environment to enter the container.
