  "id": "MLC-T-CHM-005734",
  "term": "Impregnation",
  "field": "Chemistry",
  "definition": "A process where a porous solid material is permeated by a liquid or a substance in solution, which then remains within the pores after the solvent is removed. In chromatography, this involves loading a liquid stationary phase onto a solid support to create the separation medium. The term also describes the introduction of additives, such as plasticizers or flame retardants, into a polymeric material to modify its properties.",
