  "id": "MLC-T-CHM-007005",
  "term": "Mass-average particle diameter",
  "field": "Chemistry",
  "definition": "A statistical measure of particle size in a dispersed system, calculated by considering the mass contribution of each particle size fraction. It is obtained by summing the product of the mass fraction of particles within a given size range and the mean diameter of that range. This average is sensitive to larger particles in the distribution.",
