Description
Summary:The influence of the nature of sorption phases on the microweighing parameters of volatile organic compounds sorbed from gases and vapors is investigated using microstructural methods. The mechanism of interaction between nitrogen-containing compounds and universal polymeric and solid-phase specific sorbents is found. The roughness parameters of piezoelectric-resonator electrodes are estimated before and after the deposition of thin sorbent films and during the sorption and desorption of nitrogen-containing compound vapors. Recommendations on how to employ piezoelectric resonators with films for identifying different compounds of gas and air mixtures are presented.
