The GBPI GTR-10N is a specialized laboratory gas permeation analysis system designed for quantitative permeation measurement, gas selectivity evaluation, and barrier profiling of polymer membranes, inorganic barrier coatings, multi-layer packaging films, and technical sheeting. Built in strict conformance with standardized equal-pressure chromatographic gas permeability methods including ISO 15105-1, ASTM D1434, and JIS K7126, this high-performance system couples an advanced permeation test cell with an integrated Gas Chromatograph (GC) utilizing an ultra-stable Thermal Conductivity Detector (TCD).
Accurate understanding of multi-gas transmission behavior is critical for modified atmosphere food packaging (MAP), industrial gas packaging, and membrane separation development. Conventional single-component gas sensors cannot analyze mixed gases simultaneously. Operating as a state-of-the-art gas permeation analysis system, the GBPI GTR-10N overcomes these analytical hurdles by testing pure gases as well as multi-component gas blends composed of nitrogen (N&sub2;), carbon dioxide (CO&sub2;), oxygen (O&sub2;), and helium (He). Under precise temperature and pressure conditions, permeating gas molecules are swept by a carrier gas into a specialized packed chromatographic column, where distinct components are separated based on adsorption affinity and quantified at the TCD detector cell.
High-Precision Inorganic Gas Permeation & Selectivity
The GTR-10N is optimized specifically for non-combustible inorganic barrier testing. It enables membrane scientists to simultaneously determine individual transmission rates and calculate permselectivity ratios (α = P1/P2) across different gas pairs, providing critical empirical data for gas enrichment membranes and high-barrier barrier packaging.
Integrated Thermal Control & Standalone Touchscreen
The system features an integrated liquid bath jacket maintaining cell test temperature from 15 °C to 60 °C with ±0.1 °C stability, while feed gas pressures are regulated up to 300 kPa. The GC unit incorporates an intuitive color touchscreen terminal for temperature ramp programming and status monitoring.
The companion PC software workstation delivers automated baseline tracking, continuous chromatographic peak integration, automated multi-point calibration, and tamper-proof PDF reporting conforming to ISO 17025 and GMP quality standards.
