Determination of kinetic characteristics of molecule thermodesorption on the surface of oxidated molybdenum

Abstract

Adsorption and surface ionization (SI) of morphine molecules С 17 Н 19 NО 3 with (m/z 285) on the surface of oxidized molybdenum was studied by voltage modulation method (VMM) with a high-vacuum mass spectrometric setup using a "black chamber" with all walls cooled with liquid nitrogen. The SI mass spectra and temperature dependences of ion current of C 9 H 7 N + CH 3 radical with m/z 144 were obtained by ionization of morphine molecules on the surface of oxidized molybdenum by using stationary SI method.
