GBPI Y310L – 3-Chamber Coulometric Oxygen Permeability Analyzer (OTR)

The GBPI Y310L is an advanced laboratory-grade coulometric oxygen permeability analyzer engineered for the quantitative oxygen barrier characterization of plastic films, composite laminates, coextruded barrier sheets, and pharmaceutical packaging materials. Built in strict accordance with ASTM D3985, ISO 15105-2, ASTM F1927, ASTM F2622, DIN 53380-3, and JIS K7126-2, this three-station testing instrument provides packaging converters, resin manufacturers, and accredited test houses with exceptional measurement accuracy and analytical stability.

Oxygen barrier performance is paramount in preventing oxidative rancidity, microbial proliferation, and nutrient degradation in modified atmosphere packaging (MAP), pharmaceutical blister packs, and sensitive electronic displays. The GBPI Y310L coulometric oxygen permeability analyzer utilizes the standardized coulometric sensor method: a prepared test specimen is clamped between an upper oxygen chamber and a lower carrier gas chamber. High-purity dry nitrogen sweeps through both chambers to establish baseline equilibrium, after which high-purity oxygen gas is routed to the upper test cell. Driven by the partial pressure gradient across the barrier membrane, oxygen molecules permeate through the material into the nitrogen stream, which conveys them directly into an electrolytic coulometric fuel cell sensor. Within the sensor, each oxygen molecule generates four electrons, producing a quantitative electrical current strictly proportional to the oxygen transmission rate (OTR).

Three Independent Parallel Test Chambers

To maximize testing throughput, the GBPI Y310L features three completely independent test stations housed under a panoramic inspection cover. Technicians can execute tests on three duplicate specimens concurrently to generate compliant statistical averages, or analyze three distinct barrier formulations simultaneously without risk of mutual gas cross-contamination.

Integrated Touchscreen & Dynamic Environment Control

The Y310L incorporates an articulated industrial Windows touchscreen terminal, facilitating standalone parameter input, real-time curve monitoring, and onboard data storage without mandatory workstation coupling. An automated thermal jacket regulates cell temperature between 15 °C and 45 °C with ±0.2 °C precision, while a dual-circuit gas humidification system dynamically controls relative humidity from dry 0% RH up to 100% RH saturation.

The system software delivers automated baseline drift correction, certified reference film calibration protocols, multi-tier operator authority levels, and audit logs compliant with pharmaceutical GMP and FDA 21 CFR Part 11 requirements.
