Laser Particle Sizer ANALYSETTE 22

This note describes the applications of laser diffraction for the determination of particle size distributions. Two examples of particle size distribution in food and beverage samples are presented.

1. Particle size distribution of homogenized milk (red) and cream (blue) measured with an ANALYSETTE 22 NanoTec.
2. Particle size distribution of four different types of chocolate samples with an ANALYSETTE 22 NanoTec.

Medium-hard to hard materials with edge lengths up to 95 mm can be pre-crushed with the FRITSCH Jaw Crusher PULVERISETTE 1 so an additional fine comminution with many FRITSCH mills is possible. Particle size and surface area are very important for a number of applications - this application note explains the grinding process and how to optimize your particle size to your application.

The development of below sea level deposits offshore of the west coast of the Antarctic Peninsula was strongly influenced by the variation of the continental ice shield and the amount of ice in the ocean, which also influenced the global climate. With core-depth drillings, these variations can be backtracked over periods of several millions of years. This application note shows the use of the ANALYSETTE 22 for particle sizing of these deposits.

This application note presents a fast method for the qualitative and quantitative analysis of mineral composition. Sample comminution and homogenization methods are described.

This application note describes the analysis of the particle size distribution of ampicillin, a semi-synthetic antibiotic from the group of beta-lactam antibiotics (penicillin), using the analysette 22 Compact.

Procaine is a local anaesthetic - an ester type - which is used very seldom today as a local anaesthetic, since much more effective and more deeply penetrating substances, where allergic reactions are less occurring. However, procaine is still used in the neural therapy, a type of treatment from the areas of alternative or animal medicine. This application note determines procaine particle size distribution, measured using the ANALYSETTE 22 Compact with a small volume dispersion unit.

Many properties of different material systems are significantly influenced by the particle size distribution of the original raw material. These may be relevant parameters for the manufacturing process as well as for the quality of the final product. This application note explains how to choose the right type of Fritsch particle sizer according to your needs.

This application note addresses the importance of sample preparation in the measuring process of particle size. A mixture consisting of about 800 g of quartz sand was created and divided using the FRITSCH Rotary Cone Sample Divider with a rotary sample divider. Results demonstrate the LABORETTE 27 to be superior to conventional sample dividers.

This application note investigates the optical characteristics of opaque materials. The measurement of particle size distribution of ground cryolite using FRITSCH’s ANALYSETTE 22 is given as an example.

In addition to discussing why particle size analysis is so important and discussing the techniques that are currently available to measure particle size, this application note from Fritsch highlights the importance of sample dispersion. Methods for both wet dispersion and dry dispersion are presented.

Convenient – precise - reliable!
