<p>A flame based method for analyzing a sample by introducing the sample into a combustible gas mixture, igniting the combustible gas mixture to produce a flame, and detecting a characteristic of the resulting flame to determine the identity and/or concentration of one or more chemical substances in the sample, wherein the combustible gas mixture is a premixed hydrogen and oxygen gas mixture generated by water electrolysis. The same method is also utilizable for determining the identity and/or concentration of one or more chemical compounds in the sample. A flame based detector apparatus for analyzing a sample is also described. The apparatus includes an inlet for introducing a premixed combustible gas mixture therein, a feeder for introducing the sample into the premixed combustible gas mixture, an ignitor for igniting the combustible gas mixture to produce a flame, a detector for detecting a characteristic of the resulting flame for determining the identity and/or concentration of one or more chemical substances in the sample, and a water electrolyser for generating a premixed combustible gas mixture and for directing the gas mixture to the inlet. <IMAGE></p> |
