Micro UV Aerosol Detector

The detection of aerosols within fluid samples can be accomplished by optical methods. Such methods are useful in detecting potentially harmful aerosols such as biological aerosols that may be present after a biological agent attack or industrial accident. It is well known that biological molecules fluoresce when...
