The gas chromatograph which uses the hydrogen flame ionization detector and its detector

摘要

Topic Increasing the ionization efficiency of the sample by the hydrogen flame, it improves detection sensitivity. SolutionsFID has the nozzle 2 in order to burn up hydrogen in the Tip. Hydrogen being ignited with the Tip of nozzle, 2 the hydrogen flame is formed, the sample which is sent from channel 4 burning up by the hydrogen flame, is ionized. Ion collector 10 is laid out to surround the hydrogen flame in the upper part of nozzle 2. In order to surround ion collector 10 outside ion collector 10, the coil 14 which generates the uneven magnetic field where magnetic field strength becomes strong facing toward the hydrogen flame is laid out. Oxygen gets together in the hydrogen flame with the influence of the magnetic field where it is generated by coil 14, energy density of the hydrogen flame rises. Choice figure Drawing 1
