ASAS - Aerosol Size and Shape technology

Characterisation by size, concentration and especially particle shape is a powerful means of distinguishing between a potential threat and benign interferents such as pollen and diesel fuels. ASAS technology has been deployed by the military for several years to provide protection against aggressors perceived to be in possession of Biological Warfare Agents.

VeroTect uses the combination of light induced fluorescence, together with particle size and shape information to characterise the aerosol to an extent that is not currently achievable by any other real time sensor. The result is a high level of discrimination between threat and interferents and a correspondingly low level of false alarms, thus increasing end user confidence.

The VeroWarn bio-detection software provided with the sensor is based around a common algorithm core offering a range of operator interfaces from a simple yes/no indication to a sophisticated analysis package for research use.
