Laser diffraction is currently the most efficient process for the determination of particle size distributions in a wide measurement range (10 nanometres to multiple millimetres). The solid samples are dispersed either dry into the air stream (powder) or wet in liquid (suspension).

The advantages of this technology are found in very short measuring times, automated processes (calibration, measurement procedure, cleaning) as well as high precision and reproducibility of the measurement results.

The almost unlimited opportunities for processing of the results also represent an advance compared with typical methods of particle size analysis.

With the four analysette 22 laser particle sizers as well as the wide range of accessories, FRITSCH offers an optimal configuration for almost every application.

The analysette 22 NanoTec covers the "high-end" range of extremely small particle size measurements. It is available with optional software for particle shape recognition.

The analysette 22 COMPACT with its excellent price/performance ratio is the ideal basic model. It is suitable for laboratories switching from the typical methods (sieving, sedimentation, image analysis) as well as for newcomers to particle size analysis.

The analysette 22 MicroTec fits perfectly in between and covers the intermediate range of applications.

The analysette 22 MicroTec XT with a measuring range of 0.1 to 2,000 µm is the measuring instrument for samples in the millimeter- and submicron-range.
