• Description:
  A program for developing, designing, fabricating, and laboratory testing two prototype instruments capable of real time selective detection and measurement of airborne fibrous shaped particles is described. The operation of this fibrous aerosol monitor (FAM) is based on the rotation imparted to the acicular particles by means of a rotating quadrupole electric field of the order of 3,000V/cm. This field induces a dipole charge separation on the fibers and aligns them with the applied field. The selective detection of the fibers is effected by synchronous detection of the resulting modulation of the light scattered from a continuous wave helium/neon laser beam by the rotating particles. The theory of operation, design of the electric/optical detection configuration and the electronic signal processing method are discussed. It is maintained that concentration of the order of one fiber per cubic centimeter can be assessed by this aerosol monitor. [Description provided by NIOSH]
