Abstract: A flame ionization detector including means for monitoring the flame condition, so as to enable ignition of an extinguished flame. An igniter coil is mounted proximate the burner nozzle of the FID, and thermocouple means are provided including a hot junction in thermal contact with the nozzle, and a spaced cold junction. Means are provided for applying an electrical potential to the igniter coil to enable ignition of the flame upon a flame-out condition being detected as measured by the thermocouple output. In a preferable embodiment, the ends of the igniter coil are connected to a pair of electrical leads, with the connection zones defining the hot and cold junctions of the thermocouple. This permits the same lead pair to provide both the potential enabling the igniter function of the coil, and the interconnection for the thermocouple output signal. The same lead pair may also be utilized to provide the biasing potential to the burner nozzle.
