Popis: We report here the experimental investigation of lightly sooting methane premixed flames with and without hydrogen. Two different approaches were considered to introduce hydrogen in the methane flame, either by keeping the total gas flow rate constant or not. Speciation data were obtained using a set of analytical tools including Gas Chromatography, Fourier-Transform Infrared Spectroscopy, Jet-Cooled Laser-Induced Fluorescence, Laser-induced Incandescence coupled with Cavity Ring-Down Spectroscopy. The results include mole fraction profiles of gaseous species (C0-C16) and soot volume fraction (fv) measured in all studied flames. These results demonstrate that the introduction of hydrogen to the flame insignificantly impacts the maximum mole fractions of small species (
