• LASER DIFFRACTION• DYNAMIC LIGHT SCATTERING• IMAGE ANALYSIS

Results from number based systems, such as micro-scopes or image analyzers

Results from laser diffraction construct their beginning result as a volume distribution. The software for many of these systems includes the ability to transform the results from num ber to Volume.

an example where a laser diffraction result is trans-formed from volume to both a number and a surface area based distribution.
