Optimization of the Number of Detector for a Low Angle Laser Light Scattering (LALLS) Particle Size Distribution Analyzer
The number of detector elements is a critical factor in determining the accuracy and resolution of a Low Angle Laser Light Scattering (LALLS) particle size distribution analyzer. On the other hand, the particle size resolution also strongly depends on an algorithm that is used to invert the scattering data. Therefore the comparison of competing instruments involves investigation of both factors acting simultaneously. In this paper, we tested a resolution of bi-modal distribution by computer simulation for the standard optics with different types of detectors. The theoretical scattering of data is calculated by the use of Mie scattering theory. The distributions resulting from the inversion of the scattered data by the non-linear iteration method are compared. Three different types of detectors, containing 21, 42 and 81 elements respectively, are then investigated to compare the computer simulation results. These measurements were determined for a mono-dispersed sample of polystyrene latex (PSL).
