Nozzles applying the structure of the detector for a gas chromatograph

摘要

(57) [summary] [purpose] in a gas chromatograph for the detector that employs a nozzle application system, to easily perform like the maintenance of the nozzle. [Configuration] The nozzle 14 capable of producing a flame, it opposed the detectable collector 23 the signal current in the interior of the mounting body 1. And insulates the nozzle 14 from the mounting body 1 is applied a high voltage, to form a high electric field between the nozzle 14 and the collector 23. Is disposed inside the insulating block 10 which is constituted by the conductive portion 12 and internal and external to the insulating portion 11 of the mounting body 1 and insulated from the mounting body 1 inside of the conductive section 12 the block 10 via the external of the insulating portion 11 to. As well as connecting the high voltage power supply terminal 16 to the conductive portion 12, to attach the nozzle 14 detachably by separating the high voltage power supply terminal 16 to the conductive portion 12.
