METHOD OF DE-SORPTION/IONIZATION OF CHEMICAL COMPOUNDS Russian patent published in 2006 - IPC G01N27/62 

FIELD: analysis of gaseous and liquid media.

SUBSTANCE: method can be used for solving problems of matrix-free method of de-sorption/ionization of chemical compounds by using ion emitters with active layer produced for reproducibility, which layer provides high-sensitive quantitative analysis of gaseous and liquid media in real time. Method of de-sorption-ionization of chemical compounds, intended for usage during subsequent mass-spectrometric determination, is based upon formation of active layer onto surface of substrate, onto application of molecules of chemical compounds onto it by means of adsorption or deposition, and onto subsequent ionization and de-sorption of ions from surface of substrate due to influence onto substrate by electromagnet radiation or by flux of particles. Formation of active layer of substrate includes creation of split chemical bonds in volume of substrate and/or onto its surface with concentration no lower than 1014 cm-3 by means of introduction of structural disordering of substrate's surface, or deposition of nano-sized particles onto surface of substrate either creation of amorphous layer of material onto surface of substrate.

EFFECT: improved precision of analysis of gaseous and liquid media.
