520  ‎$a‎The use of a Coulter counter model TA is described for measuring the volume distributions of coal-mine dusts collected by the MRE gravimetric sampler. Trisodium orthophosphate as an electrolyte has been found to give good dispersion of the dust, and a 50 nm diameter orifice gives a satisfactory size coverage for MRE dust samples. The instrument is best calibrated using suspensions with known volume concentrations
