There has been a major increase in quality control techniques used for powders and granulates during the past few years. This has resulted in more analysis procedures with a continuing decrease in staff numbers available in the laboratory to do this work.
This has created the need for measurement methods, which are faster, easy to use and more reliable than those currently in use. The main objective is to acquire as much data as possible in the shortest time possible to characterise the powder under test.
AnaTec produced the first PartAn Particle Size Analysis system over 20 years ago and during that period the system has been developed and upgraded to keep pace with developing technologies. The current hardware is state of the art electronics and the software is fully compatible with all the latest versions of MS Windows.
Based on the experience of the past 20 years in particle technology and image analysis, AnaTec has developed a new photo-optical particle analyser the new Fine Particle Analyser (FPA).
The sample particle size and shape is measured with a two full frame high-speed cameras, which give a measurement range for the FPA of 1 to 5,000 microns. The FPA cameras give two size ranges for coarse and fine particle size distributions. The FPA has a much higher resolution in comparison to other photo-optical systems. The FPA operates using high speed, high-resolution cameras which have a theoretical resolution of 48 million Pixels per second.
The sample is measured fully automatically in a dry state and does not require any form of sample preparation. With the special de-agglomerating sample feeding system the FPA is able to disperse and measure even highly cohesive powders.
AnaTec developed our special feeding system in conjunction with the high-speed light source for the FPA. This combination makes it possible to analyse particle size and shape down to 1 micron.
The benefit in using the FPA in comparison to Laser Methods is that the user obtains information about particle size and shape within one analysis.
The FPA was developed and is available for Online and Laboratory based measurements.

The FPA is easy to use and gives reliable and repeatable results. All data is logged, printed and can be transferred into LIMS or database software packages.
