has specified output desorption measurements thermal desorption spectroscopy TPD temperature-programmed desorption TDS CHMO:0002673 https://orcid.org/0000-0001-5985-7429 2010-01-13T10:27:27Z A method of observing desorbed molecules from a surface when the surface temperature is increased. The sample is heated slowly in a vacuum and residual gas in the vacuum is detected as a change in pressure. temperature programmed desorption thermal desorption spectrum
