A method of nonoxidation detection of NO in breath is developed as an alternative to the expensive chemiluminescence technique. For this purpose the comparative characteristics of sensors, developed on the WO3 and ZnO basis and intended for defining nitric oxide microconcentrations in exhaled air, have been investigated. The impulse temperature mode of operation was used for sensor working. The mathematical method of sensor signals processing in presence of other exhaled air background gases was applied. The minimization of sensors quantity for gas component analysis makes simplify mathematical processing of results at certain experiment conditions. The threshold of sensitivity to NO is equal to 10 ppb. A monitoring device for measuring NO in breath has been made. It is complex system with of sample preparation block, measuring block and special software. First tests have been fulfilled at medical institute. |
