    A high-sensitivity, compact set-up, which bases on a photonic bandgap fiber (PBG) and enables the precise measurement of low concentration of gas was designed. Besides high sensitivity, the priority was put on a low cost, portability and simplicity. Proposed technique allows reducing gas sample volume to 0.01 cc. The micro-capillary gas flow inside photonic crystal fiber was estimated. Darcy - Weisbach equation for non-compressible flow and quasi - Panhandle equation for compressible gas flow were used for the calculation of gas flow rate and gas velocity. During the experimental work several types of PBG fibers of various parameters were specially designed, produced and used. The core diameters ranged from 10.9 um to 700 μm.
