Abstract

This paper presents new experimental results on the sensitivity of a microstructure fiber (MSF) to toluene and ethanol in gaseous mixtures with nitrogen. This sensitivity is compared with that determined with a single-capillary fiber (CF). The results obtained both with the fibers modified by a porous detection layer prepared by the sol-gel method from tetraethoxysilane are presented. MSF with air holes arranged in one shell and coated with an UV acrylate jacket was prepared by using the "stack and draw" technique. CF coated with polydimethylsiloxane optical cladding was prepared. The segments of the prepared fibers were modified by a porous polysiloxane layer applied onto the hole walls. The sensitivity of the MSF and SCF to gaseous toluene and ethanol in nitrogen was determined from spectral changes of C-H and O-H absorption bands in a range of 1300-1800 nm. Limits of detection of 0.008 and 0.02 vol.% have been determined for toluene and ethanol, respectively.
