Software Features

Eliminates the mistake or trouble of selecting refractive indices Particle size distribution data and light intensity distribution data can be displayed in real-time

This means that changes in the sample over time or shifts in the dispersion status can be monitored in real time. Since both the light

Note: 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 Continuous measurement of 1-second interval particle size changes
the "Kinoshita Method", in academic communities, after the name of Shimadzu’s engineer.
Changes in particle size distributions and particle diameters are measured continuously, at intervals as short as 1 second, and the results
are saved. Furthermore, the results can be subjected to multifaceted analysis and evaluation using functions such as 3D graphing. For
Assist function decreases operational error to ensure more accurate measurement
example, the reaction processes that occur when particle groups disperse, aggregate, or dissolve can be monitored

Measurement Assistant Functions: allow preparing SOPs to ensure measurements are always performed using the same
conditions and procedures.
Creating, saving, and sharing measurement conditions and
procedures, including pretreatment methods and conditions,
ensures measurements are performed using the same conditions Normalized Particle Amount (Diff)
and procedures, even if performed by a different operator or at a
different location or plant, and allows safely comparing data.
Furthermore, when the measurement assistant function is used,
measurement instructions for the operator are displayed on the Particle Diameter (µm)
screen. This enables even inexperienced operators to perform
measurements correctly. In addition, administrators and operators
can be assigned different operating privileges to ensure security.

Note: SOP is an acronym for Standard Operating Procedure. conditions and procedures (SOP)
Procedures, remarks, and other information
are displayed interactively during
measurements. This standardizes measurement
procedures and prevents mistakes. This is an example of light intensity distribution data and particle size distribution data for the dissolution process of calcium carbonate.
It shows how dissolution progresses from smaller diameter particles and how the normalized amount of large particles increases.
