ABSTRACT:
A flame head for a flame photometric detector is disclosed comprising an explosion-proof housing having a combustion chamber therein defined by a fused quartz tube flame wall barrier. Means are provided for securing a fiber-optic bundle to the housing with one terminal end of the fiber-optic bundle positioned adjacent the fused quartz tube whereby light emitted from the combustion chamber can be transmitted via the fiber-optic bundle to a photomultiplier and associated electronic detection means remotedly located therefrom. A burner tip communicates with one end of the fused quartz tube and provides gas effluent and fuel through a passage therein coaxially aligned with the quartz tube while providing required air to four circumferentially spaced ports disposed about the passage. Means are also provided for purging fuel from the area immediately adjacent the terminal end of the fiber-optic bundle adjacent the quartz tube.
