Krichmar, Registration Date 26-03-2003 Organization Kherson state technical university popup.description2 Research job is devoted to studying of processes in electrochemical sensors with the purpose of creation of the most sensitive and selective gas and liquid sensors. The basic laws on which job of devices depends are revealed. It has enabled to create gas sanitary sensors with damp electrodes for definition dioxide nitrogen with sensitivity 1 х 10-7 % vol., and also acid and alkaline gases. Last sensor enables to define ammonia on equal 0,5 х 10-4 % vol. and hydrogen chloride gas at a level 0,5 х 10-5 % vol., that exceeds maximum concentration limit in 2-3 times. It is created conductivity a sensor for measurement of small volumes of electrolits in industrial and household liquid objects, which allows spending measurements conduction liquids on constant and an alternating current from volume in some microlitres. The original techniques of sampling and measurement conduction have been offered. The sensors for definition of acidity of environment in a drop of a solution with quinhydrone a detector electrode have been developed.
