High purity nitrogen generatorThe core lies in air separation technology, which separates 78% of nitrogen in the air from other components such as oxygen and carbon dioxide through physical or chemical methods, achieving an increase in nitrogen purity.

　　High purity nitrogen generatorWorking principle:

Electrochemical nitrogen production: Pure air that has undergone pressure stabilization treatment is input into an electrolytic cell. The oxygen in the air absorbs electrons at the cathode and reacts with water to form hydroxide ions. These ions then migrate to the anode, where they lose electrons and release oxygen, leaving only nitrogen gas flowing out along the gas path.

Pressure swing adsorption (PSA) nitrogen production: Using carbon molecular sieves as adsorbents, nitrogen is separated from air through pressure swing adsorption at room temperature. Carbon molecular sieves have selective adsorption differences for nitrogen and oxygen. Oxygen molecules are more adsorbed on the surface of carbon molecular sieves, while nitrogen molecules are less adsorbed. By alternating adsorption and regeneration processes, continuous output of nitrogen is achieved.

Membrane separation for nitrogen production: Utilizing special polymer membrane materials to differentiate the permeability of different gas molecules, when compressed air passes through the membrane, oxygen and other impurity molecules are intercepted by the membrane on the permeate side, while nitrogen molecules are enriched on the retention side of the membrane, thereby achieving nitrogen separation and purification. However, the nitrogen purity of this method may not reach high-purity levels.

This device can replace high-pressure nitrogen cylinders, reduce safety risks, and operate fully automatically. It is easy to operate and maintain on a daily basis. Some parts also come with casters, making it easy to move. Modular structural design saves laboratory space.
