The U.S. Army is seeking information on portable systems capable of detecting and identifying vapor and aerosol chemical hazards. The system should be one-person portable, detect and identify traditional Chemical Warfare Agents (CWAs) and Non-Traditional Agents (NTAs), and have a Mean Time Between Operational Mission Failure (MTBOMF) of not less than 370 hours. The system should also be capable of remote operation and alarm via an application hosted on a tablet computer. • The system should have a volume of 0.85 cubic foot or less and a weight of 18 pounds or less, including internal batteries. • The system should detect and identify vapor and aerosol traditional Chemical Warfare Agents (CWAs) at very low levels. • The system should detect and identify aerosol Non-Traditional Agents (NTAs). • The system should have a Mean Time Between False (positive) Alarm (MTBFA) of not less than 50 hours. • The system should be capable of continuous operation when using host platform or fixed-site power sources. • The system should be capable of operation for 12 continuous hours when using DoD inventory batteries.
