Lighthouse Active Air Sampler Technology and d50

Air Sampler impaction technology has been around for decades. However the d50 is a little know aspect of air sampler technology design and it plays a critical role in air sample capture.

Aerosol Impaction is the process in which particles are removed from an air stream by forcing the gases to make a sharp bend. Particles above a certain size possess so much momentum that they cannot follow the air stream and strike a collection surface such as a media plate which is available for later analysis of composition after an incubation period.
