Particle sizer method same as laser diffraction method? #15

Open gwemon opened 1 year ago

The definition of particle sizer as an analytical method for particle size distribution does not mention laser diffraction. Should it? Have all particle sizers used the laser diffraction method up until now? From a quick search this seems to be the case. See e.g. https://en.wikipedia.org/wiki/Particle-size_distribution https://www.labcompare.com/Laboratory-Analytical-Instruments/32-Particle-Size-Analyzer-Particle-Analyzers-Particle-Sizer/ but see also https://www.atascientific.com.au/particle-size-analysers-work/

S04 already contain terms for laser diffraction method: laser diffraction dry laser diffraction wet laser diffraction
