Detection of hydrocarbons using suspended core microstructured optical fiber

Popis výsledku v původním jazyce

Monitoring of dangerous hydrocarbons is an important issue for both chemical process control in industry and protection of the environment. Vapors of toluene are highly dangerous in low concentrations because of its low explosive limit of 1.2 mol%. Toluene vapors in concentrations lower than the explosive limit can be detected using a fiber optic arrangement containing a short section of suspended core microstructured optical fiber (SC MOF). We prepared the SC MOF for this purpose, with an inner structure consisting of a relatively thin silica core, 2.6 ?m in diameter, surrounded by three large cladding holes with radii of 26 ?m, which were designed to be large enough for trouble-free analyte flow. It has been shown that a 0.3 m-long SC MOF sensing element can be used for refractometric detection of toluene vapors in low concentrations without using any other adsorption layers. We have experimentally verified the operational reversibility of the SC MOF sensing element in time. A sensit
