Available Analytical procedure and to determine the size of particles Suspended in a liquid medium

摘要

A method and an arrangement for Measuring the size of particles in Media Solution based on the spectroscopic Analysis of the intensity of Light backscattered by a sample when illuminated with White Light.The technique used is based on the Fourier analysis and comparison between the backscatter Spectrum obtained Experimentally and theoretically for different Radii of the particles. Given the one-to-one correspondence between the two Fourier Transforms (TF), it is possible to generate a Calibration Curve u00f4radio vs Particle.Maximum tfu00f6, suitable for determining radius of particles in samples polydisperse Solutions. In addition, Treatment of Data by Cross Correlation allows to increase the accuracy in the determination of the average Radii of the particles present in the sample.
