  "id": "MLC-T-CHM-006976",
  "term": "Mass distribution ratio",
  "field": "Chemistry",
  "definition": "The ratio of the total mass of an analyte in the stationary phase to its total mass in the mobile phase, at equilibrium, within a chromatographic or extraction system. This value reflects the overall partitioning behavior of a substance between the two phases, considering all its chemical forms. It is a key parameter in evaluating the efficiency of separation processes.",
