FLAME IONIZATION ANALYZER, CONTROL METHOD FOR FLAME IONIZATION ANALYZER, AND FLAME IONIZATION ANALYZER PROGRAM

摘要

An onboard flame ionization analyzer 100 that is to be installed in a vehicle VH and can reliably determine when a hydrogen flame has been lit, even when used at high altitude. The flame ionization analyzer 100 has a detector D that burns gas using a hydrogen flame and detects the current generated, an ignition determination unit 92 that determines that the hydrogen flame has been lit when a detected value obtained using the detector D has exceeded a prescribed threshold value, and a variable value acquisition unit 94 that acquires a variable value that changes in accordance with the altitude or air pressure at a measurement location. The ignition determination unit 92 corrects the detected value or the threshold value on the basis of the variable value acquired by the variable value acquisition unit 94 and determines whether the hydrogen flame has been lit.
