PROCESS OF MANUFACTURE OF MODIFIER OF ELECTRODES OF PIEZO- QUARTZ RESONATOR TO DETECT VAPORS OF ORGANIC SUBSTANCES IN AIR Russian patent published in 2001 - IPC

FIELD: analytical chemistry of organic compounds, detection and analysis of organic compounds. SUBSTANCE: proposed process can be used for analysis of gas effluents of plants, specifically, for determination of concentration of aniline. Given process of manufacture of modifiers of electrodes of piezo-quartz resonator to detect vapors of aniline by piezo-quartz weighing includes modification of electrodes with toluene solutions followed by drying. Combined sorbent based on active component ( trioctylaminoxide, trioctylphosphineoxide ) and on stabilized component of polystyrene in mass proportion 1:3 and total mass 6.5-8.5 micrograms. EFFECT: increased selectivity, precision and fastness of analysis. 6 tbl
