Instrument functions

Based on oxygen paramagnetism, EZGAS6000Oxygen analyzer, industrial process, chemical and metallurgical analysisIt is a process of analyzing oxygen concentration using thermal magnetic processing technology, which is used for online or portable analysis of oxygen concentration in industrial processes and scientific laboratories. It has the characteristics of high automation, strong functionality, and digital communication.

working principle

Under the influence of an external magnetic field, matter will be magnetized and exhibit certain magnetic properties. When a substance is magnetized in an external magnetic field, it generates an additional magnetic field. When the direction of the additional magnetic field is the same as that of the external magnetic field, the substance is attracted by the external magnetic field; When the direction is opposite, it is repelled by the external magnetic field. The substance attracted by an external magnetic field is called a paramagnetic substance, or in other words, the substance has paramagnetism; The substance that is repelled by an external magnetic field is called a diamagnetic substance, or in other words, the substance has diamagnetism.

Gas media can also be magnetized in a magnetic field, exhibiting paramagnetism or diamagnetism depending on the type of gas. O2, NO, NO2, etc. are paramagnetic gases, while H2, N2, CO2, CH4, etc. are diamagnetic gases.

The volume magnetization of oxygen is much higher than that of other gases, so the paramagnetic properties of oxygen can be used to analyze its concentration.
