  "term": "Volume of the stationary phase",
  "field": "Chemistry",
  "definition": "The volume of the liquid stationary phase, or of an active solid or gel, inside a chromatographic column, with any inert solid support left out of the count. For a liquid coated on a support it is the liquid volume alone, so it is smaller than the volume of the packed bed. It appears in the retention factor k = K·Vs/Vm, where Vm is the mobile phase volume and K the distribution constant.",
