Abstract

The possibility of spectroscopic gas sensing using infrared hollow fiber as the absorption cell was demonstrated. By optimizing the coating dielectric material and fiber structure parameters, hollow fiber obtains low-loss property at the absorption wavelength band of various gases. Using low-loss infrared hollow fiber as the gas absorption cell has the potential advantages of miniaturization, high sensitivity, small gas sample volume, and thus rapid response. Several kinds of dielectric-coated silver hollow fibers were fabricated and tested for corrosive gas sensing. The durability of the fibers, with inner coating film of silver and silver iodide (AgI), cyclic olefin polymer (COP), SiO₂, polycarbonate (PC), as well as Ag tube were discussed experimentally. We used NH₃, HCl, and ammonia, hydrochloric acid as the corrosive gas or liquid. By flowing the corrosive material through the hollow fiber, durability of the fiber on these corrosives were measured. Experimental results showed that AgI/Ag and COP/Ag hollow fiber have high durability.
