Abstract
A self-contained closed loop system and method for detecting contaminants in, on, and around objects. The system includes an air duct subsystem connecting at least one sensor to a sealed housing containing a rotating container. Air from the sealed housing is circulated past a sensor to detect, for example, biological or chemical contaminants. If a contaminant is detected, an indicator is set and a contaminant neutralizer is optionally injected into the air duct subsystem.
