Biotechnix - Particle Size Determination Technology
The Biotechnix µADL (micro-aerodynamic lens) aerosol concentrator was initially designed to concentrate particles in the 1-10 micron range and deliver them in a narrow beam, one millimeter or smaller in diameter to optical particle analyzers. Coupling our µADL concentrator to a novel particle classifier that separates the concentrated aerosol stream into separate flow channels based on particle size provides the capability of size-classifying the particles.
The Biotechnix aerodynamic particle classifier sorts larger particles based on their aerodynamic diameter. Once the larger particles are removed from the flow by our µADL concentrator, the ultrafine and fine particles, smaller than 1 micron, are captured by a custom-designed electrostatic precipitator. The combination of an aerosol concentrator, aerodynamic and electrostatic size classifiers, and efficient capture of the particles leads to an effective particle sizing device for particles with sizes from ultrafine (10 nanometers) to 20 microns.
