Since 1984, Fritsch have been manufacturing laser particle size analysers. Fritsch was the first company to introduce the concept of laser diffraction in a convergent laser beam. By positioning the Fourier lens in front of the measurement cell, a convergent laser beam passes thought the measurement cell and the scattered light is focused directly on the detector without the need for additional optical elements.
Fritsch have patented the design of a movable measurement cell between the Fourier lens and the optical light scattering detectors contained within the new A22 NeXT. This means that a wide particle size distribution can be measured and adopted for many different types of sample materials.
There are two instruments:
1. A22 NeXT Micro with a measurement range of 0.5-1,500µm.
The NeXT Micro laser particle size analyser contains a single light source and a single forward light scattering detector, with a measurement range of 0.5-1,500µm.
2. A22 NeXT Nano with a measurement range of 0.01-3,800µm.
The NeXT Nano laser particle size analyser also has only a single light source, however additional light scattering detectors have been added to the instrument to detect forward, backward and sideward light scattering to increase the particle size measurement range from 0.01-3,800µm.
Key features of the A22 NeXT laser particle size analysers include the following:
The A22 NeXT laser particle size analyser has a superior wet dispersion unit with the following features:
These instruments are supplied as standard with a CPU unit (monitor, keyboard and mouse) with the MaS Control software pre-installed.
