ABSTRACT:
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 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 combustible gases therein, a feeder for introducing the sample into combustible gases, an ignitor for igniting the combustible gases 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 combustible gases and for directing the gases to the inlet.
