Sample Preparation and Sieve Analysis

RETSCH instruments are used in science and industry for the sample preparation for a wide range of different analytical methods as well as for particle size analysis in the context of production control and quality monitoring.

RETSCH meets the ever-increasing demands in these fields with a clear product philosophy: "The whole is greater than the sum of its parts"

In accordance with this principle we not only use high-quality components, but also place great value on their perfect interaction. The results are instruments characterized by their superior technology and outstanding reliability for each individual application in sample preparation and particle size analysis. This philosophy is reflected throughout the whole range of RETSCH products, which are arranged in three segments:

The Basic Principles of Sieve Analysis

Many natural and manufactured materials occur in a disperse form, which means that they consist of differently shaped and sized particles. The particle size distribution, i.e. the number of particles of different sizes, is responsible for important physical and chemical properties.

Such as:
• mechanical bulk behavior
• surface reaction
• taste
• miscibility
• filtration properties
• conductivity
This list could be continued at great length. The examples clearly show how important it is to have a knowledge of the particle distribution, particularly within the context of quality assurance in the production of bulk goods. If the particle distribution changes during the manufacturing process then the quality of the finished product will also change. Only a continuous monitoring of the particle size distribution can guarantee a constant product quality.
