Data Analysis Functions
Scattering Angle Evaluation Function Evaluates scattering characteristics within micro angle regions for samples such as optical films and sheets.
Data Emulation Functions Emulates measurement results from other instruments and measurement principles, using SALD series measurement results.
Mixture Data Simulation Function Simulates particle size distributions using any mixture ratio of multiple particle size distributions.
Data Connection Function Combines two particle size distributions with different measurement ranges at any particle size point to create a single particle size distribution.
Continuous Measurement Function Continuously measures changes in particle size distributions and particle diameters over time, at intervals as short as one second, and saves the results.

Note 5: The LDR method automatically calculates an appropriate refractive index based on consistency between the actual measured light intensity distribution and one reproduced (recalculated) from particle size distribution data. This method was developed by Shimadzu and published in two technical papers. It is sometimes called the "Kinoshita Method", in academic communities, after the name of Shimadzu's engineer.
