Any other information on results incl. tables

A test substance sample was observed to be a fine and medium off-white powder with clusters. Based on observation with a 3.2 objective lens, the particles appeared to be irregular shaped crystals. Based on observation with a 40 objective lens, the sample was observed to be made up of single crystalline particles.
