Gas membrane separation is a new and highly efficient separation technology. Compared with the previous separation, gas membrane separation technology is superior in investment, instrument and energy consumption. Meanwhile, this technology is convenient, environmental friendly and easy to operate. Owing to those advantageous factors, it has been widely applied in food, medical & pharmaceutical, petrochemical, biotechnology and environmental engineering, etc. One of the key issues for membrane separation technology and its development is the membrane material for gas separation. Ideal gas separation membrane should possess high gas permeability, excellent capability for gas selection, good heat and chemical stability and outstanding forming and processing properties. Among the above mentioned properties, gas transmission rate of respective gas content separated by the gas separation membrane is the R&D focus of manufacturers. Hereafter, Labthink will make a brief introduction to gas transmission rate testing of various contents through gas separation membrane, based on Labthink world innovative G2/110X Separation Membrane Permeability Analyzer.

1. Working Principle of Gas Separation Membrane

Gas membrane separation technology makes use of the different gas transmission rates in the gas mixture through gas separation membrane, so as to realize gas separation by collecting gas with high transmission rate at the permeated side, and collecting that with low transmission rate at the other side.

2. Working Principle for G2/110X Separation Membrane Permeability Tester

The gas transmission chamber of G2/110X Separation Membrane Permeability Analyzer is separated by the gas separation membrane at a certain temperature. Then, the operator purges gas mixture at a certain pressure into one side, and achieves vacuum at the other side. Thus, a gas pressure difference is formed between two sides of the membrane. Gas would transmit through the membrane and into the low pressure side. The gas would then be carried to the separation chamber along with the carrier gas flow. FID, flame ionization detector, would accomplish gas content measurement, and calculate gas transmission quantities of different gases through a unit area within a unit time.

Labthink G2/110X Separation Membrane Permeability Analyzer is the world innovative gas transmission rate analyzer for gas contents through gas separation membrane. Embedded with computer platform, this tester can realized gas transmission quantity testing of single gas or compound gas contents, as well as gas selection and transmission rate(s) testing. Dual temperature control of heating and cooling confirms testing at any temperature within the temperature range. Thus, it can meet the testing demands for permeability analysis and optimization of gas separation membrane.

The excellent components and reliable performance can confirm qualified gas transmission rate testing of varied gas contents through gas separation film.
