Principle:
Nano theory with full-scale, fully taking into account the refractive index of the optical properties of the particles and the dispersion medium measured particle size distribution data, depending on the size of the particles in each angle scattered light intensity changes on the anti-particle group performances.
Particle sizing calculations are generally divided into unconstrained fitting inversion and the constrained fitting inversion. Constrained fitting inversion before the calculation assumes that match a certain distribution of particle group, according to the law of inverse particle size distribution. This type of operation is relatively simple, but because of prior assumptions inevitably exists between the reality of bias, thereby testing the constrained fitting data do not reflect the actual particle size distribution of the particles.
Unconstrained fitting inversion test before the particle does not make any assumptions, by light intensity directly and accurately calculate the size distribution of particles. Such assumptions are reasonable detector and particle classification, to make high demands on the device itself. SKZ1062 laser particle size Analyzer, using optimum of non-uniform cross-dimensional fan-shaped array of detector arrays and reasonable size grading, making it possible to accurately measure particle size distribution.
