METHOD AND DEVICE OF MULTI-SENSOR DETECTING MAIN PRIORITY POLLUTANTS OF ATMOSPHERIC AIR Russian patent published in 2008 - IPC G01N27/12 

FIELD: ecology.

SUBSTANCE: device of multi-sensor quantitative detecting of main priority inorganic pollutants in atmospheric air: ammonium, sulfur dioxide and hydrogen sulfide includes multi-sensor system on superficial acoustic wave, consisting of three double lines of detention. Each detention line in double detention line represents sensor element, which is made on separate quartz crystal and is placed in separate measuring cell, sensitive coatings in form of functional polymer films being applied on all six sensor elements in space between counter-pin transformers of detention line. Sensitive coatings are by two identical in chemical structure and thickness, and differ from each other in each pair of sensor elements.

EFFECT: ensures method and device for express control (detecting) of main priority pollutants in atmospheric air at level of their dangerous for people's vital functions and (or) highly explosive and inflammable concentrations, including their (ammonium, sulfur dioxide, hydrogen sulfide) detecting at background of normal air composition and output of data about their quantitative content in atmospheric air units of concentration in mg/m^3.
