Abstract: A gas cross-sensitivity analysis method is provided. The method includes, an injection frequency signal is generated from a first gas. A second gas sensing signal is captured from a second gas. Then, the second gas sensing signal is converted to a second gas sensing frequency signal by using Fast Fourier Transform. Further, a sensing peak frequency signal is determined from peak frequency of the second gas sensing frequency signal. The injection frequency signal and the sensing peak frequency signal are analyzed. A gas cross-sensitivity effect can be direct interpretation by a singular indication between the injection frequency signal and the sensing peak frequency signal.
