Temperature-programmed desorption

{
  "id": "MLC-T-CHM-011856",
  "term": "Temperature-programmed desorption",
  "field": "Chemistry",
  "definition": "A thermal analysis technique used to study the adsorption and desorption of molecules from a surface. A sample with adsorbed species is heated at a controlled rate in a vacuum, and the desorbing molecules are detected by a mass spectrometer. The desorption temperature provides information about the binding energy of the adsorbate to the surface.",
