ABSTRACT:
The flame ionization detector includes basically a nozzle for a measuring gas fuel gas mixture and is coaxially disposed to a target electrode. Materials and dimensions for these components are critical and include a platinum metal nozzle tip, a noble metal surface target electrode, a limited range for the nozzle duct diameter, a limited range for the relative position between the nozzle tip and the lower end of the target electrode, and angle ranges for conical nozzle contour surfaces.
