The temperature-programmed desorption (TPD) method combined with mass spectrometric analysis has been applied to the characterization of glassy carbon (GC) and modified glassy carbon surfaces. Five different samples of GC were obtained from a commercial resol type of phenol formaldehyde resin that h
## Abstaact Mathematical models used to achieve the deconvolution of temperature-programmed desorption (TPD ) spectra from heterogeneous surfaces generally rely on assumptions about the pre-exponential factor or on the variation of the activation energy of desorption with coverage. In contrast, in
