We offer particle size determination by laser diffraction for materials, depending on sample and sample preparation, under ISO and GMP conditions.
This means, that particle sizes in the size range of 0.01µm-3500µm can be determined by different sample dispersion using the principle of laser light scattering. This offers, for example, a better resolution than conventional size measurement techniques (e.g. sieve analysis).
For you, this means that you can have the particle sizes determined over a large range with a high resolution compared to sieve analysis. In addition, laser diffraction is a widely used analytical method in the industry, which ensures the comparability of the measurement results.
How can we support you?
Our technique: Laser diffraction by means of Mastersizer 3000
Sample matrices: Powders, suspensions, and emulsions
We offer measurements under ISO 13320 and GMP conditions (soon also GLP under conditions).
A distinction is made between dry dispersion of powders and wet dispersion measurements of suspensions and emulsions. The measuring range for the particle size always depends on the sample.
Dry dispersion:
| Sample types: | from cohesive powders to fragile materials. |
| Sample preparation: | none, sample is added dry to the system. Agglomerates can be broken up by mechanical methods. |
| Size range: | 0.01 µm to 3500 µm |
| Required sample quantity: | min. 10 g |
Wet dispersion:
| Sample types: | Suspensions, emulsion or also powder in organic or aqueous dispersing agents. |
| Sample preparation: | Depending on the sample, the particles must be converted into a stable dispersion which can be introduced into the dispersing medium. |
| Size range: | 0.01 µm to approx. 2100 µm (the maximum depends on the dispersing module used). |
| Required sample quantity: | min. 0,5 g |
If less sample material than the required minimum quantity is available, please contact us, we will be happy to help.
The particle size measurements can be used in routine analysis as well as in research analysis. It is a fast method to determine the particle size distribution.
The particle size is important in many areas of industry. In occupational safety it is possible to make a statement about whether the examined particles are respirable and thus potentially dangerous for humans. In the context of tablet production, it is possible to predict a statement about the strength of the tablet.
Particle sizing in the nano range or imaging particle sizing can be carried out using SEM.
