Gas and Water Vapor Permeation Analysis SystemGTR-10X/30X

Gas permeability of water vapor and/or gases, such as O2, N2, and CO2 etc., under humid conditions can be measured by this single system.

This photo is an example.

This system complies with ISO 15105-1 and JIS K7126. It uses gas chromatography with a differential pressure method that can measure the gas transmission rate and permeability coefficient of gases and/or water vapor under humid conditions. It injects the permeate of test gases into the column of a gas chromatograph, separates them into each component, and calculates the gas permeability coefficient and transmission rate of the individual components. Barrier properties of water vapor and /or gases can be measured by this single system.

Features

• Gas permeability of water vapor and/or gases, such as O2, N2, and CO2 etc., under humid conditions can be measured by this single system
• Ability to measure WVTR and gas permeability coefficient simultaneously under humid conditions
• Gas chromatography with a differential pressure method
• Able to test below room temperature
• Automatic operation with a data processor
• Ability to measure the liquid permeation with the exchangeable upper parts of cells (PV cell)

Application

For measurement of gas and water vapor permeability and barrier properties of polymeric films
