Abstract
The invention relates to a flame ignition device for an analysis apparatus and a control method. The device comprises a power supply system formed by a switch power supply; an ignition system formed by a solid state relay and a glow plug; a sensor system formed by a current sensor, a glow plug temperature sensor, a flame sensor, an environment temperature sensor and an atmospheric pressure sensor;and a control system respectively and electrically connected with the switch power supply, the solid state relay, the current sensor, the glow plug temperature sensor, the flame sensor, the environment temperature sensor and the atmospheric pressure sensor. According to the device and the method, the average power, the ignition time and the ignition logic of the glow plug are controlled through the control system, intelligent ignition compensation is performed with the combination of data fed back by the sensors, and the device is advantageous in that the ignition reliability is high, the lifetime is long, electrical and ultraviolet light spectrum interferences can be avoided, and the structure is simple.
Description
technical field [0001] The invention belongs to the technical field of analytical instruments, and in particular relates to a flame ignition device and a control method for analytical instruments. Background technique [0002] In the field of detection technology related to analytical instruments, flames are widely used as a means of atomization, ionization or thermal excitation. For example, gas chromatography uses a hydrogen flame as the ionization means of the components to be measured, and provides an ion source for the flame ionization detector; at the same time, the hydrogen flame is also the excitation source of the gas chromatography flame photometric detector; the atomic absorption uses the acetylene flame, and the atomic fluorescence uses The flame formed by the combustion of argon-hydrogen flame or other combustible gas is used as the means of atomization. [0003] Flame, as an indispensable key technology for chromatographic and spectral analysis instruments, ha...
