Maximizing Soy Milk Quality Attributes through Particle Size Analysis

In this note, the final result of soy milk processing is evaluated with particle size analysis. Particle size results give a quantitative measure of the soy milk that can be used to ensure consistent production and product quality.

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.

Particle Size of Electronic Ceramic Powders

Particle size analysis plays a crucial role in the manufacture of electronic materials for dielectric applications. In all cases, the particle size distribution has a great impact on their processing and performance.

Particle Size Analysis of Drilling Fluid

This application note explains why particle size distribution is critical and how HORIBA laser diffraction analyzers can be used to measure the particle size distribution of drilling fluids.

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.

Measurement of Particle Size of Cement and Concrete Components

The final properties of the concrete body are determined by a number of properties. This note addresses the effects of particle size in cement manufacturing and in the final product.

$DLS vs. Diffraction of Flavor Emulsions$

The particle size distribution of many flavor emulsions has a substantial effect on their performance. Particle size distribution can affect mouth feel, appearance, and emulsion stability.

This application note reviews the important role that particle size plays in the formation of mayonnaise and mayo products and how changes affect the taste and consistency of these alternatives.

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.

The abrasive particles found in CMP slurries have a size distribution which directly affects critical metrics. Particle size analysis is therefore a key indicator of CMP slurry performance. The popularity and utility of several particle sizing techniques will be discussed within.

Nutraceuticals are food extracts that have been demonstrated to produce a physiological benefit or provide some protection against chronic disease. Nutraceuticals are the intersection of nutrition and pharmaceutical and can also include functional foods and dietary supplements.

Products used in ceramic and abrasive applications are invariably produced from powders. Particle size distribution has profound effects on processing and function of these products. These materials include most oxides and minerals from aluminum oxide to zirconium oxide. Depending on the application, particle size can effect densification, transport and mechanical properties.

$Measuring Organic Pigments with Laser Diffraction$

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.
