In the laboratory, nitrogen boosters will use nitrogen, such as liquid mass spectrometer ICMS, gas chromatograph GCMS, sample preparation, etc., then, let's learn about it together
The principle of nitrogen booster and precautions for use.
What is the principle of nitrogen booster?
At present, there are two main principles of nitrogen booster, they are: 1. Separation by hollow fiber membrane (low purity and small volume); 2. Separation by PSA synthetic molecular sieve (purity
high, bulky).
The technical principle of nitrogen booster is: gas molecules are usually adsorbed and dissolved on the high-pressure side surface of the membrane, and then dispersed in the membrane through the concentration gradient, and enter from the low-pressure side of the membrane.
Perform analysis so that small molecules and molecules with strong polarity pass through fast, while large molecules and molecules with weak polarity pass slowly. Membrane separation is the use of various gases to permeate rapidly in polymer membranes.
When the gas separation is carried out with the difference of the degree of separation, the separation propulsion is the gas partial pressure difference on both sides of the membrane, so the membrane gas separation has the advantages of no phase change, no regeneration, simple equipment, and easy operation.
Advantages such as low maintenance costs.

The principle of nitrogen booster: using air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption principle, using carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen
The method, commonly known as PSA nitrogen production. The laboratory PSA nitrogen booster uses air as raw material, carbon molecular sieve as adsorbent, adopts the principle of pressure swing adsorption, and uses carbon molecular sieve for oxygen and nitrogen.
A method of selective adsorption separation of nitrogen and oxygen. Compared with the traditional nitrogen production method, it has the advantages of simple process flow, high degree of automation, low power consumption, and a wide range of product purity.
It has the characteristics of adjustment to user needs, convenient operation and maintenance, low operating cost, and high adaptability of the device.
What are the precautions for using a nitrogen booster:
The principle of the nitrogen booster is explained earlier, and the precautions for the use of the equipment are also introduced here. Before use, check whether the air inlet is blocked by garbage. If so, immediately
Treatment: There is a problem with the life of the piston seal of the built-in air compressor. Please turn off the equipment in time after use; when the air source is not connected, do not run the machine without load.
