Equivalent hydrodynamic volume

  "id": "MLC-T-CHM-004080",
  "term": "Equivalent hydrodynamic volume",
  "field": "Chemistry",
  "definition": "The volume occupied by a hypothetical hard sphere that possesses the same hydrodynamic properties as a macromolecule in solution. This value is often determined from chromatographic measurements, such as size-exclusion chromatography. It reflects the effective size of a polymer chain, including any associated solvent molecules, as it moves through a fluid.",
