Biological Aerosol Threat Warning Detector
GE Global Research delivered the prototype ultraviolet (UV) biological aerosol fluorescence detector, based on light-emitting diodes. The compact and low-cost device operates continuously to detect the presence of biological aerosols by detecting UV and visible photons generated from UV-induced fluorescence. The user can select alarm set-points based on intelligence information. The system uses multiple wavelengths to increase sensitivity and reduce the probability of false alarms. An innovative flow-cell design keeps the particles from contaminating the optical components. Chamber testing conducted by the Calspan-University of Buffalo Research Center validated the performance of the system against non-pathogenic spores, vegetative bacteria, proteins, and viruses in the presence of common aerosol contaminants such as dust, tobacco smoke, and cooking oils. The system has been evaluated across a range of building environments. For additional information please fill out the Contact Information Form.
