Physical characterization of the helium-oxygen-acetylene flame as an atom cell for atomic spectrometry

Abstract: Physical characterization of a helium-oxygen-acetylene flame supported on a water-cooled burner has shown the flame to possess a high degree of laminarlty and a maximum safe operating temperature of 2760 K (with 60% helium diluent).Safe operating conditions for the flame have been established to enable Its safe and flashback-free operation. In addition, the spectral background of the flame has been examined and found to be relatively low compared to other high temperature flames, suggesting its use as a promis… Show more
