A process and apparatus are provided for detection of viable and potentially hazardous biological particles which may be dispersed in a particulate-containing airstream. The process comprises directing each of the contained particles along a linear path through air, in a sequential manner, and sampling them for determination of their size, whether they are biological and viable, and whether they are present in concentrations greater than background levels. The particle size identifies the particles as respirable or not and the particles are characterized...
Apparatus for identifying the existence of viable biological particles within an airstream containing a mixture of biologically viable end biologically inert particles, comprising: means for directing the particles individually and sequentially along a substantially linear path through air; a source emitting an ultraviolet laser beam directed to contact each particle moving along its linear path in the air, said beam having a wavelength operative to excite biomolecules contained therein to produce fluorescence; means for measuring the intensity of the fl...
