Density loops should include pressure (P) and temperature (T) measurements at the density meter (DT) and pycnometer (PYC) outlets in order to ensure equal process conditions when a pycnometer sample is pulled.
Although there are numerous methods of obtaining the density of solids in the laboratory (densitometer, pycnometer, etc.
The density is obtained by helium pycnometer (accupyc from micrometrics) and the D50 by laser granulometry using the sirocco device of the Mastersizer 2000 (Malvern).
