Multi-functional, discrete determination of concentrations of gases in a gaseous mixture

[0044]By using the methodology described herein, it is possible to detect relatively low concentrations (e.g., tens ppm, hundreds ppb) of reducing gases and, with some applied limitations, and selectively distinguish certain gases, vapors or liquids from one another.

[0045]The functioning of sensors and calculation of their parameters may be observed during a state of dynamic equilibrium. In a steady state, any small variation or oscillation surrounding the predominant average value are deemed insignificant and are thrown out from the calculation. As a result, limitations occur and the sensor's output parameters are only predictable and calculated for a particular range of changing input parameters. For example, sensors work correctly within limited changing characteristics of the sensitive layer under gas influences. Due to the influence of internal factors in the body of the sensor, such as diffusion and recombination, discarding these small changes in relation to the predominant aver
