The technology consists of a new highly sensitive and selective method of detection and analysis of gaseous organic compounds and water vapor, and of a new-generation of portable gas analyzers developed for it. The technology is designed on the basis of sensitive polymeric sense indicators combined with high-frequency piezogenerators, which detect the content of organic compounds in any gaseous mediums, including the atmosphere, with a 0,1-20 ppm accuracy, depending on the composition of the sensitivity of the polymeric coating of the indicator and its frequency characteristics.
The piezogenerators used in the gas analyzer device are characterized by high sensitivity. This is the basis for the development of the analyzer's indicator together with sensitive polymeric sensors characterized by high selectivity for the registered component during the process of its absorption in the gaseous medium. The technology know-how is in the coating of the piezogenerator to make it sensitive to the component of the gaseous medium to be detected.
The analyzer has been developed for use in detection of methane and moisture in the atmosphere. The moisture meter registers the relative change in water vapor concentration with 0.1-1ppm accuracy. Sensitivity of the same analyzer can be adjusted for the detection of methane in the atmosphere, with an accuracy of about 10 ppm.
For the detection of a variety of specific components (including toxic ones) in the atmosphere the sensitivity of the gas analyzer may be modulated to the nature of the component to be detected.
The development can be widely applied in electronics, precision engineering, production of chemical reagents, medicine, cosmetology, etc.., as well as in the field of security.
The development and production of thermosensitive and mass- sensitive resonators is based on the physical property of the piezogenerators' mass-sensitivity of orienting itself along the axes of the quartz crystal.
