GTR-TEC® Permeation Analyzers

Who is GTR-TEC®?

Introduced permeability analysis using Gas Chromatography (GC) in 1970.
Offers permeation analyzer systems to operate over the widest range of temperatures, humidity & special conditions.
Developed proprietary software for analyzing GC results

Why use GC for Permeation Analysis?

Analyze single or blended gases.
Separate blended gases into their individual components.
Analyze all gas components simultaneously and separately.
Accurately determine the permeation rate of each gas component.
Use both TCD and FID detection systems.
Analyze liquid, vapor or dry gases.
