  "id": "MLC-T-CHM-004499",
  "term": "Flow rate",
  "field": "Chemistry",
  "definition": "The volume or mass of a fluid passing through a given surface per unit of time. In chromatography, it describes the speed at which the mobile phase moves through the column, directly influencing separation efficiency and analysis time. The flow rate is typically expressed in milliliters per minute (mL/min) for liquid chromatography or cubic centimeters per minute (cm³/min) for gas chromatography.",
