Distribution isotherm

  "id": "MLC-T-CHM-003345",
  "term": "Distribution isotherm",
  "field": "Chemistry",
  "definition": "A curve or function giving the stationary-phase concentration of an analyte in terms of its mobile-phase concentration once equilibrium is reached at a fixed temperature. Depending on the retention mechanism it represents partitioning, adsorption, or a mixture of both, in every chromatographic mode, gas chromatography included. A straight-line isotherm yields symmetric Gaussian peaks, whereas a curved one produces tailing or fronting in nonlinear chromatography.",
