Laser particle sizing at the push of a button

With the new FRITSCH Laser Particle Sizer ­ANALYSETTE 22 NanoTec particle measurement becomes a simple matter, for professionals as well as for any employee – in production and quality control or in research and development. No prior knowledge is required. Just start the programme, select a SOP and add the sample, the rest takes place completely automatic – fast, reliable and efficient. Advantages are a simple operation, short analysis times and consistently reproducible and reliable results.

New optical design

The large measuring range from 0.01 µm to 2100 µm of the ANALYSETTE 22 NanoTec results from the combination of two lasers with two different measuring cell detector spacings: Large particles are detected using an infrared laser with a large distance to the measuring cell, for small particles a green laser with a small distance to the cell is used, which permits the detection of the forward scattered light up to a scattering angle of 65°. The measurement of smallest particles down into the nano range is performed by the green laser light for backward scattering. Specially arranged detectors ensure this. The total measuring range of 0.01-2100 µm in the ANALYSETTE 22 NanoTec can be detected without converting the optical elements. The results are perfect measurements with outstanding reliability, meaningful comparability and consistent reproducibility.

Intelligent modular design

The ANALYSETTE 22 NanoTec consists of a compact measuring unit that can be quickly and easily combined with different dispersion units for dry or wet measurement. The wet dispersion unit is to serve for wet measurements of solids and suspensions. For wet dispersion of very small quantities, the automatic small volume wet dispersion unit SVA with illuminated dispersion bath and the compact manual small volume wet dispersion unit SVM are available. The practical, fully automatic AutoSampler makes it easy to perform a series of measurements with the wet dispersion unit. For dry measurements of not too fine, free-flowing materials the dry dispersion unit with efficient degradation of agglomerates is available. For dry measurement of agglomerates or free-flowing materials is to serve the falling chute.

Practical fast-switch-system

The measuring cells of the ANALY-SETTE 22 dispersion modules are located in practical cartridges that can be exchanged with a single motion when switching between wet and dry measurement – without changing any hoses or modifying the instrument! Your advantage: fast and easy change of the dispersion method.

The ANALYSETTE 22 NanoTec software contains completely predefined Standard Operating Procedures (SOP) for nearly all typical measurement tasks, making operation especially easy. Via a well-arranged input mask, customers are free and flexible in modifying these SOPs to perfectly suit measurement requirements.

Perfect fully automatic evaluation

For the control, recording and perfect evaluation of measuring results the ANALYSETTE 22 NanoTec is delivered with a computer on which the FRITSCH MaS control software is already fully installed. The software MaS control is easy to learn and guides customers through the entire measurement process in a largely self-explanatory manner. In addition to integrated standard reports, the freely editable report generator allows to organise measurement reports exactly according to customers needs. For testing the FRITSCH Particle Sizers, customers can send a sample for a free of charge sample measurement, and receive a detailed analysis protocol.
