Evaluation of Gas Permeability of
Film of Volatile Organic Compounds



Film gas permeability test is generally conducted with oxygen, carbon dioxide, steam, etc. We have successfully developed a method for evaluating the gas permeability of film of volatile organic compounds that change to a gas at normal temperature. Here are the testing method and results of a permeability test conducted by the method.

Testing method

Evaluation container

Film is sandwiched between the top and bottom of the container.

Example of practice

Permeability curve of volatile compound A

It can be seen that with the passage of time, Compound A permeates through the film and moves from the bottom section to the top section of the container.

The film gas permeability of the volatile organic compound can be evaluated.
