The effectiveness of a highly sensitive sodium dodecyl benzenesulfonate (SDBS)–TiO₂ thin film optical waveguide gas sensor assessed in detecting various organic gases. Gas sensing measurements indicated that the sensing element has good selectivity, high sensitivity, and a low detection limit of 1 ppb to xylene gas with fast response and short recovery times. Interference gas test results showed that the sensitive component can detect 1 ppm of xylene gas in a mixed system containing other interfering gases, thus demonstrating the effectiveness of the proposed sensor for organic gas detection.
