Centro de Documentacion de Fundación MAPFRE - Characterization of the volume size distribution of respirable coal-mine dust samples by coulter counter

Notas: Sumario: The 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 concentrationsRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 3, December 1977 ; p. 257-270Materia / lugar / evento: Higiene industrial Contaminantes químicos Contaminación atmosférica Control de la contaminación Polvo Carbón Minas de carbón Métodos de análisis Otros autores: Rickmann, A.M.
