ABSTRACT:
A flame ionization detector is disclosed that is particularly useful for liquid chromatography. The detector is preferably utilized with a disc transport assembly with flame jets being positioned at opposite sides of the solute-bearing periphery of the disc. Hydrogen and air are injected through the flame jets and coaxial cables are connected to make electrical contact with the flame jets so that a flame ionization response occurs when organic compounds on the disc of the disc transport assembly are combusted in a potential field. When so combusted, a current is caused to flow from the flame jets through the coaxial cable to an electrometer where the current is amplified for display on a strip chart recorder or other output device.
