GBPI Y110P 2.0 Coulometric Oxygen Transmission Rate Tester for Packaging Containers

Overview

The GBPI Y110P 2.0 Coulometric Oxygen Transmission Rate (OTR) Tester for Packaging Containers is an engineered solution for precise, traceable, and regulatory-compliant oxygen barrier characterization of rigid and semi-rigid packaging systems—including bottles, BFS (blow-fill-seal) containers, laminated tubes, pouches, capsules, and blister packs. It operates on the fundamental principle of coulometric oxygen detection: oxygen molecules permeating through the package wall are swept by high-purity nitrogen carrier gas into a solid polymer electrolyte sensor, where electrochemical reduction generates a current proportional to the molar flow rate of O₂. This linear amperometric response enables direct quantification of oxygen transmission in real time, eliminating reliance on calibration curves or reference gases during routine operation. Designed specifically for package-level testing—rather than flat film only—the instrument accommodates sealed, three-dimensional geometries under controlled environmental conditions (temperature and relative humidity), making it suitable for evaluating real-world barrier performance under application-relevant stress states.

Key Features

• Modular, tool-free packaging fixture system with rapid-mount/dismount capability; supports interchangeable, custom-engineered fixtures for diverse container formats (e.g., vials, ampoules, sachets, stick packs, and coffee capsules).
• Integrated dual-mode thermal control using Peltier elements for bidirectional heating/cooling, enabling stable temperature regulation within ±0.5 °C across 15–45 °C range.
• Active humidity control via saturated salt solution-based vapor generation and feedback-regulated chamber conditioning, maintaining setpoints from 20–95 %RH with ±2 %RH accuracy.
• Large-capacity internal water reservoir (≥5 L) enabling unattended operation for up to 120 hours—critical for low-permeability materials requiring extended equilibration and data averaging.
• Full compliance with GMP Annex 11 (Computerized Systems) requirements: role-based user authentication, electronic signatures, audit trail with immutable timestamps, and 21 CFR Part 11–ready data integrity architecture.
• Intuitive touchscreen interface with programmable test protocols, automatic endpoint detection, real-time OTR curve visualization (with toggleable preview mode), and one-click report generation.

Sample Compatibility & Compliance

The Y110P 2.0 accepts intact, sealed packaging units without disassembly or flattening—preserving structural integrity and seal geometry critical to functional barrier assessment. Compatible sample types include plastic bottles, aluminum-laminated pouches, foil-backed blister cards, multilayer coextruded tubes, and hermetically sealed metal cans. The system meets all mandatory physical and metrological requirements outlined in GB/T 31354-2014 (Chinese national standard for package OTR testing) and aligns with international harmonized methods including ASTM D3985 (coulometric sensor method), ASTM F1307 (container testing), ASTM F1927 (flexible barrier films), ISO 15105-2 (gas transmission through plastics), and JIS K-7126-B. All measurements are traceable to certified reference standards supplied by GBPI’s in-house National Standard Substance Production Unit—ensuring consistent inter-laboratory comparability and regulatory acceptance.

Software & Data Management

GBPI’s proprietary OTRControl™ software provides full lifecycle data governance: from method setup and parameter validation to raw signal logging, statistical analysis (mean, SD, CV%), and GLP-compliant reporting. Each test session records complete metadata—including operator ID, environmental logs, gas pressure profiles, sensor zero/stability checks, and calibration history. Export options include CSV, PDF (with embedded digital signatures), and XML for LIMS integration. USB 3.0 port enables encrypted local backup; optional cloud-enabled LabLink™ module supports remote diagnostics, firmware updates, and centralized multi-instrument data aggregation via secure TLS 1.3–encrypted API endpoints. Audit trails are stored in write-once-read-many (WORM) format and cannot be altered or deleted without documented administrative override.

Applications

• Pharmaceutical primary packaging qualification (e.g., vial stoppers, pre-filled syringes, desiccant-containing blister packs).
• Food & beverage shelf-life modeling—especially for oxygen-sensitive products such as roasted coffee, infant formula, and nutraceutical powders.
• Medical device packaging validation per ISO 11607-1, ensuring sterility maintenance throughout distribution and storage.
• R&D of novel barrier coatings (SiOₓ, AlOₓ, nanocomposite laminates) and sustainable mono-material alternatives.
• QC release testing in contract manufacturing organizations (CMOs) operating under FDA, EMA, or NMPA cGMP frameworks.

FAQ

What gases are required for operation?
High-purity nitrogen (≥99.999%) as carrier gas and ambient air or pure oxygen (≥99.999%) as external permeant phase. Both require regulated delivery at 0.1–0.2 MPa via 1/8″ stainless steel tubing.
Can the instrument test both packages and flat films?
Yes—dual-mode configuration allows switching between package-specific and film-specific test chambers with dedicated fixtures and algorithmic compensation for geometric diffusion path differences.
Is calibration traceable to national standards?
Yes—GBPI is an authorized producer of national reference materials for barrier testing (CNAS-certified); included certified OTR standard films provide on-site verification and drift correction.
Does the system support 21 CFR Part 11 compliance?
Yes—full electronic signature workflow, role-based access control, automated audit trail generation, and data encryption meet FDA requirements for regulated environments.
What is the minimum detectable OTR for package testing?
0.00025 cm³/pkg·day, validated per ASTM F1307 Annex A1 using ultra-low-permeability reference containers.
