  "term": "Interparticle volume of the column",
  "field": "Chemistry",
  "definition": "The volume within a chromatographic column that is external to the stationary phase particles, representing the space available for the mobile phase to flow. This volume is also known as the interstitial volume or void volume. It is typically determined by injecting a non-retained compound and measuring its elution volume.",
