Product Overview

The Malvern Mastersizer 3000 is a versatile easy to use particle size analyser. It’s fast and accurate for both wet and dry dispersions including fragile and cohesive dry powders.

The folded optical design creates a compact system that requires very little bench space. The He-Ne 632.8nm laser and a blue solid state light source enables measurements from 10nm to 3500µm. A rapid 10 kHz data acquisition rate and excellent reproducibility allows even highly polydisperse samples to be measured quickly and accurately.

Particle size is measured using the technique of laser diffraction. Samples are dispersed in either a liquid or an air cell. A laser beam passes through the cell and the dispersed particles scatter the light creating a scattering pattern. The optics measure the angles and intensity of the scattered light from which the particle size distribution is calculated using Mie Theory.

The software guides users from method development through to routine measurement. Included is a Data Quality tool that uses extensive applications know-how to provide the essential quality assessment of data. A Report Designer enables users to present all the information they require in a customised format.

The Mastersizer 3000 is made up of an optical bench, one or more sample dispersion units, an optional dispersion imaging accessory and software for instrument control and data processing. The Mastersizer 3000 requires one or more sample dispersion units. To view these select the Accessories: Dispersion Units tab.

Application

Particle size analysis in the Cement Industry
In a cement laboratory, traditional Blaine measurement can be a time-consuming and prone to operator variability. The Mastersizer 3000 offers highly automated particle size analysis with extremely high reproducibility and repeatability. Complete size distributions can further understanding of how certain size fractions correlate with performance which makes it possible to control and optimise milling and minimise both energy consumption and operating costs.

Measuring the particle size of foods such as dairy, margarine, chocolate, coffee, sugar etc.
Particle size measurement is essential in the development of new products, during manufacture and for final QC. Particle size distribution can affect taste, appearance, texture, processability, functionality and/or the stability of the final product.

Investigating the dispersion of dry powders and APIs
Control of particle size is critical during the formulation and manufacture of pharmaceutical products. Particle size can influence dissolution, solubility, bioavailability and stability. The unique design of the Aero S dry powder disperser avoids particle-to- wall collisions leads to gentle but effective dispersion, extending dry measurement to more fragile powders.

Importance of particle sizing of powder coatings, paint, inks and pigments
Powder coatings are dry powder polymers that contain pigments and are usually applied electrostatically as a free flowing dry powder and then heated to flow into a hard finish.  To produce a consistent coating the powder must be free-flowing and have a controlled particle size distribution which can be measured simply and rapidly by laser diffraction, using a dry dispersion method.

Classify soil texture using laser diffraction particle size analysis
The Mastersizer 3000 can be used in soil analysis to rapidly determine clay, silt and sand fractions to classify soil texture which as a result guides their use and efficient management.

Characterisation of Battery Materials
An important aspect in the design of the battery material is the particle size and particle size distribution of the materials used within the electrodes. Small particle size electrodes increase the rate of electrochemical reactions while large larger particle sizes increase energy storage capacity. Using a mixture of coarse and fine battery materials is one way to meet the requirements for power and storage capacity.
