Applicant's summary and conclusion

Conclusions:
Tests were conducted dispersing the sample labelled as Mandelic Acid using the specific sampling unit called SCIROCCO 2000.
The figure shows the average volume diameter as well as that for which the accumulative particle size distribution assumes a respective value of 90%, 50% and 10% in addition to the differential distribution for each fraction and the corresponding graph as well as the measurement parameters and the indications of the powder sample and the operator. The average volume diameter is found as well as that for which the accumulative particle size assumes a respective value of 90%, 50% and 10%.
