It is half a century with the gas permeability device.

In 1970 Kyoto, Japan-based GTR Tec Corporation (then a division of Yanagimoto Seisakusho Co) ushered in a new age in the field of permeability analysis. With the introduction of analyzers that used gas chromatography systems to analyze results, for the first time it became possible to simultaneously analyze blended gases, accurately determining the rate of permeation of each individual component. Since then, the company has kept up with the changing demands of its clients, developing systems that operate over the widest possible variety of temperatures, humidity levels and other specialized operating conditions….in short, providing the perfect permeability analyzer for each client’s application.
