The basic process of a size distribution measurement is always the same: First of all, a so-called background measurement is carried out during which the signals of all detector elements are recorded without sample material being fed in. This makes it possible to record soiling of the measuring cell, for example, to be calculated out later.

Afterwards the software prompts the user to feed sample material into the dispersion unit. During this process the system continuously provides feedback by means of the so-called beam absorption whether the required sample quantity has been reached yet or still more material needs to be added. Once the proper quantity has been reached, the actual measurement data acquisition takes place automatically with subsequent calculation of the particle size distribution. Afterwards, following a freely programmable time, the process of the measurement data acquisition with subsequent results calculation can be repeated multiple times in a loop. Thus, the reproducibility of the measurement can be easily checked.
Afterwards the sample system is emptied automatically and the system is filled with fresh liquid.
