ABSTRACT:
The disclosed apparatus and methods allow collection of concentrated samples of content in shipping packages without unsealing the package by forcing airflow via existing hidden gaps or, if necessary, creating one by a small incision. The air is injected into the hidden gaps by either probe or socket device to disturb and agitate contents inside the package, causing the contents to loosen and blending particulates on the surface into the air stream. Airborne particles are channeled into a detection device, where the particulates are concentrated. Display and warning apparatus receive and record the analysis results from the detection device. If the analysis finds that predetermined selection and sensitivity criteria for target hazard or contraband material are met, then the warning apparatus initiates the appropriate alert protocols.
