  "term": "Osmometry",
  "field": "Chemistry",
  "definition": "A technique used to determine the number-average molar mass of polymers by measuring the osmotic pressure of a polymer solution. This method relies on the colligative property of osmotic pressure, which is proportional to the number of solute particles in a given volume of solvent. It is particularly effective for polymers with molar masses up to approximately 1,000,000 g/mol.",
