I'm looking for someone who is using a photooptical
System for the analysis of sand/gravel or aggregates (like
Haver CPA http://www.wstyler.com/cpa.htm or Hydros PartAn http://www.sci-tec-inc.com/partantest.html).

It is my task to compare the "traditional" sieve analysis with such a "modern" photooptical system. What could be the best way to compare these two methods?
So if you hava any expierences with such a system, please let me know (post or mail).
