Overview
The HARKE HK-G106 Gas Permeability Tester is a precision-manufactured instrument engineered for quantitative determination of gas transmission rates through polymeric and composite barrier materials using the vacuum (manometric) method. This technique relies on measuring the pressure rise in a sealed downstream chamber following establishment of a defined upstream gas partial pressure differential across a conditioned test specimen under controlled temperature and humidity conditions. The system operates in strict accordance with gravimetric and manometric principles outlined in ISO 15105-1 and ASTM D1434, ensuring traceable, reproducible results essential for quality control, R&D validation, and regulatory submissions in packaging, pharmaceuticals, medical devices, and advanced material development.
Key Features
- Triple independent test chambers (standard configuration), enabling parallel evaluation of heterogeneous samples under identical environmental conditions for improved statistical robustness.
- High-resolution vacuum sensing (0.1 Pa resolution) coupled with dual-stage pressure regulation for precise control of upstream/downstream differentials between −0.1 MPa and +0.1 MPa.
- Modular thermal management architecture supporting external chiller/heater integration—enabling stable temperature control from 5 °C to 95 °C (±0.1 °C accuracy) to simulate real-world storage and distribution conditions.
- Automated pneumatic clamping system ensures repeatable sample mounting with minimal operator intervention and zero risk of seal-induced measurement artifacts.
- Three configurable test termination logic modes: proportional threshold, fuzzy logic-based stabilization detection, and fixed-duration protocols—optimized for both high-barrier films and highly permeable elastomers.
- Expandable measurement range up to 160,000 cm³/m²·24h·0.1MPa with optional calibration kits and auxiliary flow modules—suitable for evaluating ultra-low-permeability metallized films as well as porous membranes and rubber compounds.
- Hazardous gas compatibility (e.g., H₂, CH₄, NH₃, C₃H₈) available via factory-configured safety interlocks, explosion-proof components, and dedicated gas-handling firmware—requires formal hazard assessment and pre-delivery engineering review.
Sample Compatibility & Compliance
The HK-G106 accommodates rigid and flexible planar specimens up to 5 mm thick, including aluminum foil laminates, PVDC-coated PET, coextruded multilayer structures, pharmaceutical blister foils (PVC, cold-forming aluminum), battery separators, biodegradable polymers, aerospace-grade composites, and vulcanized rubber sheets. Circular or rectangular samples (minimum 150 mm × 94 mm; active area 48 cm²) are secured within stainless-steel diffusion cells rated for repeated thermal cycling. All mechanical and software functions comply with ISO/IEC 17025 requirements for testing laboratories and support audit-ready documentation per FDA 21 CFR Part 11 when paired with HARKE’s optional GLP-compliant data acquisition suite. Instrument validation packages—including IQ/OQ documentation, uncertainty budgets per GUM (JCGM 100), and standard reference material (SRM) traceability—are available upon request.
Software & Data Management
Built-in embedded controller with touchscreen interface provides real-time graphical monitoring of pressure transients, temperature stability, and calculated permeation curves. Exportable ASCII and CSV datasets include raw sensor outputs, time-stamped environmental logs, and derived coefficients: oxygen transmission rate (OTR), nitrogen transmission rate (NTR), carbon dioxide transmission rate (CO₂TR), diffusion coefficient (D), solubility coefficient (S), and permeability coefficient (P = D × S). Optional PC-based HARKE PermeaSoft v4.2 supports multi-instrument network deployment, automated report generation (PDF/XLSX), electronic signatures, audit trails with user-level permissions, and integration with LIMS platforms via HL7 or RESTful API. All software modules undergo periodic cybersecurity hardening and maintain compatibility with Windows 10/11 LTSB environments.
Applications
- Pharmaceutical packaging qualification per USP <671> and YBB00082003 for blister cavities, pouches, and cold-forming foils.
- Food packaging shelf-life modeling using OTR/CO₂TR correlation with accelerated aging studies.
- Development and benchmarking of high-barrier coatings (SiOₓ, AlOₓ, DLC) on PET, PP, and cellulose substrates.
- Characterization of lithium-ion battery separators for electrolyte vapor transport and thermal runaway mitigation analysis.
- Permeation screening of medical device membranes (e.g., wound dressings, dialysis filters, artificial skin substitutes).
- Regulatory submission support for EU MDR Annex I (General Safety and Performance Requirements) and ISO 10993-12 biocompatibility assessments.
- Quality conformance testing against incoming material specifications per ISO 2556 and GB/T 1038.
FAQ
What gas sources are required for operation?
Users must supply certified, oil-free, dry compressed gas (O₂, N₂, CO₂, etc.) at 0.3–1.0 MPa via an 8 mm OD quick-connect fitting. Gas purity must meet ISO 8573-1 Class 2 for particulates, water, and oil content.
Is humidity control integrated into the HK-G106?
No—relative humidity conditioning is not built-in. For RH-dependent permeation studies, external saturated salt chambers or dynamic vapor sorption (DVS) modules must be interfaced upstream of the test cell.
Can the instrument be validated for GMP environments?
Yes—when configured with HARKE’s 21 CFR Part 11-compliant software package, full IQ/OQ/PQ documentation, and third-party metrological certification, the system meets ALCOA+ data integrity criteria for regulated manufacturing.
What maintenance intervals are recommended?
Vacuum pump oil replacement every 500 operating hours; O-ring inspection and lubrication every 6 months; annual calibration of pressure and temperature sensors using NIST-traceable standards.
Does the HK-G106 support custom test protocols beyond standardized methods?
Yes—the embedded scripting engine allows users to define non-linear temperature ramps, stepwise pressure gradients, and multi-phase diffusion kinetics models compliant with Fickian and non-Fickian transport theories.
