General Description
DCI-I is a complete biological, chemical and radiological detection, collection and Identification system. It combines into a 19” rack mount chassis a laser induced florescence (LIF) detector, wetted walled plastic cyclone collector (WWPC), a rapid presumptive identifier based on “Canary” technologies, and an interface to a confirmatory PCR identifier. This system also scales optional interfaces to government chemical detectors and industrial radiation detectors using existing and established software drivers to these devices. The DCI-I includes a video surveillance option that allows triggered events to be correlated with live video recording and real-time image recognition.
Technical Description
A laser induced florescence detector (LIF) searches for bio signatures examining each particle for the presence of metabolites by correlating size and florescence. If a statistical match occurs, the detector triggers the presumptive “CANARY” identifier and a wetted wall plastic cyclone collector (WWPC), which efficiently collects airborne aerosolized particulates into a phosphate buffer solution. The system provided video monitoring of the location for play back and determining the source of the event. The system communicates to authorities through network software as it prepares samples for on-site confirmatory and forensic PCR analysis.
