Multi-functional, discrete and mutually exclusive method for determining concentrations of gases in a gaseous mixture
First Claim
1. A method for determining a concentration of a component of a sample, the method comprising:
- [1] trapping a volume of the sample in a trapping chamber;
[2] passing at least a portion of the trapped volume of sample into a sensing chamber, wherein the sensing chamber includes or is in connection with a sensor;
[3] detecting a change in current as a result of interaction of the sample with a sensor;
[4] using at least Mathieu'"'"'s Equation with a value for each of its initial conditions, to determine when a value associated with the detected current is in a stable domain;
[5] when the value associated with the detected current is not in a stable domain, varying one or more of the initial conditions of Mathieu'"'"'s Equation, and repeating the determining until the detected current is in a stable domain; and
[6] determining the concentration of the component of the sample using the value associated with the detected current.

Abstract
Method and device for detection and quantitative and qualitative analysis of components in a gaseous mixture distinguished by high selectivity and high resolution.
Method allows to distinguish the influence of individual gases, by themselves or in a mixture, on the microstructure of a sensor'"'"'s sensitive layer and utilizing the variations of measured parameters to analyze and derive the characteristics of gases, for example, the concentration of a gas or multiple gases in a mixture.
As an example, the method could be utilized in medicine for non-invasive detection of the blood glucose level in diabetics.
Device realizing the method is described.
