In advanced-node CMP applications, scratch defects are often caused by the agglomeration of slurry abrasive particles, that have the potential to become a key factor in process yield performance. Our technology enables customers to perform particle size analysis online and in real time, directly in the fluid stream process. Intervening early prevents costly yield excursions.
Droplet size and zeta potential are critical indicators of emulsion stability. The AccuSizer® system is the most sensitive system for detecting tails that indicate poor emulsion stability or formulation. The particle size and zeta potential of the emulsion droplets are important physical characteristics that influence emulsion stability.
The AccuSizer® system detects oversize particles in inks and paint. The particle size of pigments used in inks and 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.
The isoelectric point (IEP) of a dispersion is the pH value where the zeta potential equals zero. This is the condition that is least stable and frequently leads to agglomeration for suspensions and phase separation for emulsions. The Nicomp® DLS system is ideal for determining zeta potential vs. pH.
A liposome is a spherical vesicle having at least one lipid bilayer used for drug delivery. Most liposomes are measured using dynamic light scattering (DLS) technology such as our Nicomp® DLS system. Larger liposomes have been successfully analyzed using our the AccuSizer® SPOS system, which uses single particle optical sizing (SPOS) technology.
Measure protein size, charge, and aggregation. The Nicomp® DLS system has the sensitivity to measure monomers, dimers, and trimers at small sizes and at low concentration – including lysozyme at 0.1 mg/mL. The AccuSizer® SPOS system is used for USP <787> testing and to study protein aggregation.
