Some particle analyzers do not include a free fall model, a non-inclusion that can be frustrating for individuals of a certain temperament when they wish to analyze samples in their naturally agglomerated state. Investigator Pam Razin writes to inform us the the Cilas model #118o does not suffer from this deficiency. Its manufacturer explicitly states:
The 1180 includes a free fall module for customers wishing to analyze samples in their naturally agglomerated state.
Razin supplies no corresponding data — that is, he supplies a non-agglomeration of data — as regards other models and makes of particle-size analyzers.
