  "id": "MLC-T-CHM-007990",
  "term": "Nominal linear flow",
  "field": "Chemistry",
  "definition": "The average velocity of the mobile phase through an unpacked column or an empty tube, calculated by dividing the volumetric flow rate by the cross-sectional area of the column. This parameter provides a theoretical measure of the mobile phase speed. It is distinct from the actual interstitial velocity within a packed column.",
