PARTICLE STANDARD AND METHOD OF CALIBRATING OR VALIDATING ANOPTICAL PARTICLE ANALYZER

摘要

The present invention provides a particle standard including particles havin g optical properties similar to those of a carrier in which the particles are dispersed, as well as a method of calibrating or validating a subject optical particle analyzer with respect t o a reference optical particle analyzer by using the particle standard. In the method, the particl e standard is analyzed with the reference optical particle analyzer to obtain a reference particle concentration and a reference particle-size distribution. Analogously, the particle standard is analyzed with the subject optical particle analyzer to obtain a subject particle concentration and a subject particle--size distribution. The subject particle concentration and the subject particle-si ze distribution are then compared to the reference particle concentration and the reference particle-size distribution, respectively, and the subject optical particle analyzer is adjusted accordingly.
