Liquid-phase film thickness

{
  "id": "MLC-T-CHM-006697",
  "term": "Liquid-phase film thickness",
  "field": "Chemistry",
  "definition": "The average distance across the stationary liquid layer in a chromatographic column, through which solutes must diffuse to interact with the stationary phase. This parameter influences the efficiency of separation by affecting mass transfer kinetics. A smaller film thickness generally leads to faster equilibration and improved resolution in gas-liquid chromatography.",
