A new research apparatus for characterization of low‐pressure premixed flames has been developed. This instrument incorporates several spectral techniques in one apparatus so that various diagnostic techniques can be quantitatively compared and the usable detection range expanded. Features include detection by mass analysis with a triple quadrupole mass spectrometer and by laser techniques such as laser‐induced fluorescence. Temperature profiles of the flame both with and without the mass spectrometer probe were obtained by thermocople. Concentration profiles of the highly reactive flame species H˙, O, and OH˙ were obtained and compared.
