ATHINA Biological Security System (ABSS) | Chemring Detection Systems

General Description
The ATHINA Biological Security System (ABSS) is an integrated solution for biological security missions requiring detection, collection, sample preparation, and identification of biological threats. The ABSS utilizes CDS's All Threats and Hazards Identification and Notification Architecture (ATHINA) to integrate sensing and support components based on the Common CBRN Sensor Interface (CCSI) Standard. The system is ruggedized and suitable for on scene and site monitoring. The sensing components of ABSS have been partitioned into three physical packages: an intelligent collector module, a manual identification module, and an electronics module. The intelligent collector continuously samples the air, upon detection of a biological event the collector warns and performs an automatic sample collection. Modules can be networked for enhanced performance. The manual identification module provides the sample preparation and identification capabilities needed to identify potential threat material. Identification is achieved by utilizing PCR and immunoassay technologies with options for automated and guided manual sample preparation. The electronics module utilizes CDS's ATHINA to provide power management, operator interface, and networking infrastructure to operate the system.

Technical Description
The intelligent collector is triggered by a UV LED Laser Induced Fluorescence (LIF) detector which runs continuously. Sample collection is accomplished with a high efficiency dry sampler developed for the collection of airborne particulates, especially pathogenic bacteria and spores. Liquid samples are extracted from the collector’s electrets filter using a manual particle extractor to release the captured aerosols. Identification is accomplished by utilizing PCR and immunoassay technologies with options for automated and guided manual sample preparation. The system can be tailored or configured for mission-specific requirement simply by changing individual sensor modules.

Notes:
This system can be combined with the Luminex MAGPIX and is being tested as part of the DoD's JUPITR ATD.
