Colloids characterization

Technique/Measurement Analysis mode Sample
CHDF/ Particle size distribution Calibration required  (range 50-800 nm) Polymeric dispersion (0.5-2 wt%)
Disk centrifuge (DCP)/ Particle size distribution Range (100 nm to 10 micron) Polymeric dispersion (< 0.5 wt%)
Dynamic Light Scattering(DLS)/ Average Particle size Range (3 nm to 2-3 micron) Polymeric dispersion (diluted)
