GC-MS study of thermal desorption of immobilized biological active substances

Abstract

The thermal desorption of different biological active substances immobilized on the surfaces of
inorganic salts and oxides (calcium hydroxyapatite, titania, alumina and silica) have been studied by GSMS
and TDMS (thermal desorption mass-spectrometry). It was investigated the processes of desorption,
destruction and thermal oxidative catalysis of biological active substances containing amine-, carboxyand
hydroxy- groups, aromatic and heterocyclic fragments.
