| titleOfInvention | Analysis of particle characteristics |
| abstract | The invention relates to an apparatus for the analysis of characteristics of individual particles originating from an aerosol or other suspension of particles and which comprises: a diffusion chamber (15) comprising an ellipsoidal reflector (17) provided with a port leading to a rear chamber (20); a monochromatic light source (10) adapted to transmit a collimated light beam (11) along the main axis of the reflector (17); elements (26, 27) for directing a stream of particles through the light beam (11) and substantially constituting the main focus (60) of the reflector (17); a ccd video camera (36) having a two-dimensional array of a plurality of detectors arranged to image light scattered from a particle in the particle stream; an optical system (17, 32, 33, 34) arranged to collect light scattered from a solid angle of at least 3. around the region where the particle stream passes through the light beam (11); and a data processor (37). The detector (36) is associated with an image reproduction screen (35) positioned such that the rays of light scattered from the particle and imaged on the screen by the optical system (17, 32 , 33, 34) are uniformly ordered with respect to the angle of scattering of the rays from the particle; the rear chamber (20) contains a detector element (25) for detecting scattered light not captured by the optical system (17, 32, 33, 34) and thus determining the presence of a particle in the light beam (11), the element (25) forming part of a trigger triggering the video camera (36) to record an image associated with the particle; and the data processor (37) is adapted to compare the parameters of the image with the parameters stored in a memory, to determine the nature of the particle. |
