Laser Diffraction Analysis of Measurement of Ink Dispersions
A number of additives in ink are usually included to modify viscosity, drying, stability, or color characteristics. Particle size of the pigment particles can significantly affect the color strength, surface finish, and durability of the final product.
Laser Diffraction Analysis of Dimethicone-treated Chromium Oxide Green
Chromium oxide is a green material. The dimethicone treatment adds a degree of “slip” to the particles allowing for better color saturation.
Size Analysis of Colloidal Silica
Most size measurements of colloidal silica are performed using dynamic light scattering instruments such as the SZ-100 Nanoparticle Analyzer. The LA-960 Laser Diffraction Analyzer can uniquely measure down to the 30 nm size range, so this laser diffraction instrument is also an option for such tests.
Pigment, Powder Coating, and Ink Particle Size
A broad collection of pigment, powder coatings, and ink products exist in particulate form in both the raw materials and finished products. The particle size distribution of these materials determines their appearance, quality, functionality and processability.
Colloids and Particle Characterization
A colloid is typically a two phase system consisting of a continuous phase and dispersed phase. The particle size of the dispersed phase typically ranges from 1 nanometer to 1 micrometer. Examples of colloidal dispersions include solid/liquid (suspensions), liquid/liquid (emulsions), and gas/liquid (foams).
Measuring Organic Pigments with Laser Diffraction
Particle size is a critical physical characteristic of pigments and laser diffraction is the most popular method of particle size analysis for the milling process, allowing close control and optimization of a number of final product performance criteria.
Particle Analysis of Gold Nanoparticles
Nanoparticle gold is a suspension of sub-micron gold particles typically dispersed in water. Gold nanoparticles are of great interest for researchers in many fields due to their unique physical and optical properties. These properties change with the particle size distribution, so size analysis is an important measurement requirement.
Sizing Silica Particles by DLS
In this application note, the particle sizes of two different silica dispersions are analyzed to demonstrate the utility of the SZ-100 for both suppliers and users of such materials.
Particle Size Analysis of Inks
Measuring the particle size of ink pigments was typically done using dynamic light scattering (DLS). Laser diffraction can also now be used to measure these pigments due to the state of the art enhancements in the LA-960.
Titanium Dioxide Particle Size
Titanium Dioxide (TiO2) is a pigment used in paints and many other applications. The particle size of titanium dioxide directly impacts its performance in numerous applications, necessitating the measurement and control of this important property.
Pigment Particle Size and Hiding Power
Pigment size can be readily measured by laser diffraction. This measurement requires less time, training and effort than a color strength measurement and provides useful information for the process engineer.
