Developed gas analizing technology is based on the use of highly sensitive semiconductor chemical gas sensors in combination with selective adsorbents for the preliminary concentration of the target gas componentы. Developed sensitive materials of the sensors are nanocomposite compounds doped with catalytic components to ensure specific sencitivity to the particular gas molecule.  Adsorption materials for preconcentration are based on highly porous silicon oxide structures with active target adsorption sites for the particular molecule.  Such an approach makes it possible to significantly improve both sencitivity and selectivity of the gas devices and systems on their basis.
