The AccuSizer detects the oversize particles in inks & paint
The particle size of pigments used in inks & paints is an important physical characteristic that affects both appearance and functionality. This is particularly true for inks used in inkjet cartridges where large particles could plug the jets and channels.
Popular technique for inks & paint
The AccuSizer is a popular particle size analysis technique to measure the size distribution of inks. Customers with a high sample throughput often pair the AccuSizer with the Autosampler for automated analysis.

Inkjet Ink Filtration Tests Ink jet inks are made of colloidally stable pigments. In order for proper deposition onto paper the ink must successfully traverse microtubing within the ink cartridge. When these colloids become unstable and agglomerate or coalesce the tubing clogs and the cartridge fails to deposit ink. To combat this issue ink manufacturers…
Backscattering DLS is used to characterize inks Inkjet inks are nanoparticle dispersions which can be characterized by Dynamic Light Scattering (DLS) . Inkjet inks are usually formulated at much higher concentrations than can be normally analyzed with Dynamic Light Scattering DLS without dilution. It is possible to analyze inkjet inks at higher concentrations when the…
