    Background calculations for new high-sensitivity gas concentration measuring method were performed. Darcy - Weisbach equation for non-compressible flow and quasi - Panhandle equation for compressible gas flow were used for the estimation of gas flow rate and gas velocity inside Photonic Bandgap Fiber (PBG). Several types of PBG fibres of various parameters were designed and used. Core diameters ranged from 10.9 to 19.9 μm. Microcapillary gas flows and gas concentrations inside fibers were measured.
