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.

Gas and Water Vapor Permeation Analysis 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
