New Laser Particle Sizer with an extremely wide Measuring Range

With a total measuring range of 0.01–2000μm in a single instrument, the Laser Particle Sizer ANALYSETTE 22 NanoTec plus from Fritsch GmbH is the ideal, universally applicable Laser Particle Sizer for effective and reliable determination of particle size distributions in production and quality control as well as in research and development. Innovative laser technology makes it possible to separately select 5 different measuring ranges. For elegant measurements with maximum flexibility, highest resolution, outstanding sensitivity and perfect results down to the nano range.

With the ANALYSETTE 22 NanoTec plus, you can choose between three measurement positions of the measuring cell, allowing measurements in 5 different measuring ranges without modification.

Regardless of the measurement position you select, the ANALYSETTE 22 NanoTec plus always uses all 57 measuring channels of the detector. By combining the various measurement positions, it is possible to perform measurements with up to 165 effective channels.

To extend the particle size determination down to the nano range, it is necessary to detect the light that scatters backward. The Fritsch solution for this is a third laser beam that utilises backward scattering for the measurement. This beam irradiates the sample positioned directly in front of the detector through a micro-hole in the centre of the detector.

Any particle size measurement is only as good as its dispersion. For this reason, Fritsch have developed the ANALYSETTE 22 NanoTec plus as an especially practical modular system with perfectly conceived units for dry and wet dispersion. When switching between wet and dry measurement, the measuring cell, which is located in a practical cartridge, can be easily exchanged, without changing any hoses or modifying the instrument. The cartridge you are not using now, can be easily stored within the dispersion unit.
