Abstract
In optical fiber spectroscopy research, adsorbent is frequently used on gas sensing detection. But traditional solid adsorbent have some adverse effect for optical transmission. In this paper, liquid film is used as the CO adsorbent. The base tube is hollow core waveguide. Liquid is coated to the inner surface of the hollow core waveguide. And the both end of the tube are packaged to FMA905 connector. The surface of the liquid film is smooth. So it has small scattering and high detection efficiency. The sensor with 48cm length is used to CO detection. The limit detection concentration can be achieved about 20 ppmv.
