Development of the Measurement and Analysis System of Nanoparticles Size Distribution

Abstract:

The measurement and analysis system of nanoparticles size distribution was developed by using virtual instrument technology, while the photon counting technology was applied in the system to replace the expensive correlator. High speed photon pulse counter was designed. The real-time data of nanoparticles dynamic light scattering were analyzed in the mixed program of MATLAB and LabVIEW, where the time autocorrelation functions of nanoparticles light scattering signals of monodisperse and polydisperse are reversed by NNLS arithmetic. Experiments results show that the peak position, peak width and symmetry of inverse distribution are very close to the real simulate particles.
