Abstract:
A flame ionization detector burner, comprising:a housing having a flame cavity therein having a length extending along a generally longitudinal axis of the housing and a housing exterior with intake passageways communicating between the housing exterior and the flame cavity for passing fuel, air and sample flows into the flame cavity and an exhaust passage communicating between the housing exterior and the flame cavity for passing exhaust gasses out of the flame cavity;a burner carried in the flame cavity receiving the fuel, air, and sample flow generating a flame to ionize the sample;an ion collector plate spaced away from the burner carried in the flame cavity collecting sample ions and providing an electrical output representative of the sample ions to the housing exterior via an electrical feedthrough between the flame cavity and the housing exterior; andthe housing further comprises at least two sidewalls removably joined together along the generally longitudinal axis of the housing and in a direction of the length of the flame cavity.
