The PolySense team has just published a new article on Molecules journal reporting on the realization of an innovative near-IR sensor exploiting a novel fiber-coupled ADM and a custom fiber combiner for sequential detection of methane and ethane in air. A minimum detection limit of 0.76 ppm for methane and 34 ppm for ethane at 100 ms of integration time was achieved. The following link provide access to the article.
