ABSTRACT:
Flame ionization detector in which the burner consists of electrically conductive material, preferably a noble metal, and is one of the electrodes in the apparatus. The mixture of fuel gas and sample is ignited by passing a current through the burner to incandesce the same. The burner is preferably a hairpin-shaped capillary tube with an aperture in the hairpin bend, disposed in the upper part of the detector with the aperture facing the bottom part of the detector. There is also described a flame trap for preventing propagation of flame into discharge line and facilities connected to it. The detector is designed to meet extreme requirements for dependability and reliability, such as when used in apparatus for monitoring anesthesia in patients.
