MODEL D type analyzer

It also has nitrogen in argon, never seen before. Usually, the detector of the current online nitrogen analyzer in argon basically adopts the analysis principle of photomultiplier tube and photocell. Plasma emission spectra.

The sensor of the SB4-TN-201 online trace nitrogen analyzer in argon adopts an electron migration sensor. At present, the electron migration sensor is the most ideal sensor for measuring trace nitrogen in argon at home and abroad. After the nitrogen impurity component in the argon gas enters the electron migration sensor, it collides inelastically with the free electrons in the sensor, causing the electrons to lose energy and increase their migration speed along the anode direction. A corresponding microcurrent is output at the collector of the sensor. The current signal amplified by the microcurrent amplifier is proportional to the component content within a certain range. By selecting an appropriate polarization voltage, the sensor only has a strong response to trace amounts of nitrogen in argon, and its response to other impurity components can almost be ignored. 　 2.
