Introduction to the factors why laboratory nitrogen generator can replace traditional equipment

This is a new type of air separation method. It uses compressed air as raw material, synthetic molecular sieve as adsorbent, gas chromatography separation and adsorption process, at room temperature and low pressure, the use of oxygen and nitrogen in the air in the molecular sieve Diffusion speed is different, oxygen and nitrogen are separated, the purity of nitrogen and gas production can be adjusted according to customer needs.The generated gas flow rate is stable, the nitrogen is purified thoroughly, and the produced nitrogen has high purity. The highest purity nitrogen can be 99.9995%. The laboratory nitrogen generator is suitable for various gas chromatography detectors.

The laboratory nitrogen generator is an instrument that uses high-pressure air to separate high-purity nitrogen in a high-precision hollow fiber membrane separation column. In the hollow fiber membrane separation column, nitrogen and oxygen molecules in a dense space composed of fibrous membrane materials are used. The passability is different. When high-pressure air passes through the membrane material, a nitrogen concentration difference is formed on the inlet side and the outlet side. The sequential passage of multiple membrane materials in the membrane separation column amplifies this concentration difference. Both ends show the separation of nitrogen from other gases in the air, and the air passes through the membrane separation column to obtain high-purity nitrogen.

The laboratory nitrogen generator uses imported hollow fiber membrane tubes to separate nitrogen, and two sets of oil-free air compressors are built in to work alternately. The air passes through a precision filter to remove water and particles in the air, and then clean air is fed into the hollow fiber membranes. Obtained high purity nitrogen.The product has the characteristics of large gas production, small size, long life and energy saving. The laboratory nitrogen generator replaces the traditional inconvenient nitrogen tank. From the aspect of safety performance, it is considered that the nitrogen is generated in a low pressure state, without the need for a high-pressure bottle or a liquid nitrogen tank.It is simple to operate, as long as you press the switch, you can continuously produce high-purity nitrogen. The operation is stable and reliable. It can be unattended for 24 hours. It can run without any trouble without any supervision and low maintenance. It replaces Traditional nitrogen tank.

Introduction

The high purity nitrogen generator is made according to the principle of air separation by electrocatalytic method, and the electrolytic cell is designed by the reverse process of the fuel cell.

As a pressure stable and pure raw material air enters into the electrolytic pool, the oxygen in the air is absorbed at the cathode and gains electrons. It interacts with water to form hydroxide ions, which are transferred to the anode, where it loses electrons and precipitates out oxygen. Therefore, the oxygen in the air is continuously separated.Only nitrogen is left to follow the air path.

Features:

Improved double-cathode stainless steel electrolytic separation tank can produce nitrogen by electrolysis and discharge oxygen synchronously, and the electrolyte circulation is smooth.

The electrolytic separation tank has a large electrolytic area, low temperature, large gas production and higher purity of nitrogen.

The unique anti-liquid backflow device ensures that no liquid backflow occurs in the instrument.

Equipped with the function of stabilizing and automatically closing the air circuit after power failure.

Advanced switching power supply is adopted to improve the efficiency of electrolytic separation.

Small size and light weight.
