Overview
The AGC MAP-PAK Combi Headspace Gas Analyzer is a dedicated, portable gas analysis instrument engineered for rapid, non-destructive quantification of oxygen (O₂) and carbon dioxide (CO₂) concentrations in modified atmosphere packaging (MAP) headspace. Utilizing electrochemical sensor technology with dual-gas detection capability, the device operates on the principle of selective amperometric sensing—where O₂ and CO₂ diffuse through permeable membranes into electrolytic cells, generating current signals proportional to partial pressure. Nitrogen (N₂) is inferred as the balance gas (100% – [O₂% + CO₂%]), consistent with standard MAP gas composition reporting protocols across food and pharmaceutical packaging validation. Designed specifically for inline quality assurance and laboratory-based shelf-life studies, the MAP-PAK Combi delivers repeatable, traceable measurements under ambient conditions without requiring carrier gases, vacuum pumps, or external calibration gases during routine operation.
Key Features
- Simultaneous dual-gas measurement of O₂ and CO₂ in headspace with independent sensor channels and real-time cross-sensitivity compensation
- Backlit high-contrast LCD display enabling clear readability in low-light production environments or cold storage rooms
- Measurement range spanning 0.1–100% for both O₂ and CO₂, supporting full-spectrum analysis—from ultra-low O₂ (80%) bakery or cheese packs
- ±1% full-scale accuracy validated per ISO 11671:2020 (Determination of residual oxygen and carbon dioxide in modified atmosphere packaging) and aligned with ASTM F2096–22 requirements for package integrity verification
- Sub-10-second response time from needle insertion to stabilized reading, enabling throughput of >300 packages per shift in QC labs
- Onboard data logging capacity for up to 5,000 timestamped measurements, each tagged with operator ID, product ID, batch number, and pass/fail status
- User-configurable alarm thresholds with visual (LED) and audible alerts, supporting automated go/no-go decisions per internal SOPs or customer specifications
- Robust mechanical design with IP54-rated enclosure, integrated needle guard, and ergonomic probe holster for field durability and operator safety
Sample Compatibility & Compliance
The MAP-PAK Combi accommodates rigid and semi-rigid food-grade packaging formats including thermoformed trays, sealed pouches, flow-wrapped bundles, and blister packs. Its stainless-steel sampling needle (included, 5 pcs) and replaceable PTFE membrane filters (100 pcs) ensure compatibility with moisture-rich, fatty, or particulate-laden headspaces without sensor fouling. All consumables meet FDA 21 CFR §177.1520 (olefin polymers) and EU Regulation (EC) No 1935/2004 compliance for food contact materials. The analyzer itself conforms to IEC 61010-1:2010 for electrical safety and carries CE marking under the EU Machinery Directive 2006/42/EC. Calibration certificates (traceable to NIST standards) are supplied with each unit, and the system supports GLP/GMP-aligned audit trails when paired with MP Download Software.
Software & Data Management
MP Download Software provides secure, encrypted transfer of measurement datasets from the MAP-PAK Combi to Windows-based PCs. The application enables batch export to CSV or Excel formats, custom report generation (including statistical summaries: mean, SD, min/max), and integration with LIMS platforms via ODBC drivers. Audit trail functionality logs all user actions—including parameter changes, calibration events, and data deletions—with timestamps and operator authentication. Software configuration supports 21 CFR Part 11-compliant electronic signatures when deployed in regulated pharmaceutical packaging environments. Firmware updates are delivered via USB and verified using SHA-256 checksums.
Applications
- Real-time validation of MAP line fill integrity in fresh meat, seafood, and ready-to-eat meal production
- Shelf-life modeling support by correlating headspace O₂ drift with microbial growth kinetics (e.g., Clostridium botulinum inhibition thresholds)
- Pharmaceutical secondary packaging verification for oxygen-sensitive biologics and lyophilized products
- Supplier qualification audits requiring documented evidence of residual gas compliance per ISO 22000 or BRCGS Packaging Standards
- In-process troubleshooting of gas flush inefficiencies, seal leakage, or barrier film degradation
FAQ
Does the MAP-PAK Combi require daily calibration?
No—factory calibration remains stable for ≥6 months under normal use; however, a quick zero/span verification using certified gas standards is recommended before each shift in GMP-regulated settings.
Can the device measure nitrogen directly?
No—N₂ is calculated as the balance gas (100% – O₂% – CO₂%) based on volumetric assumptions standard in MAP industry practice.
Is the MP Download Software compatible with macOS or Linux?
No—it is Windows-only (Windows 10/11, 64-bit), but exported CSV files are platform-agnostic.
What maintenance does the electrochemical sensor require?
Sensors have a typical service life of 18–24 months; replacement kits (O₂ + CO₂ dual-sensor module) are available with recalibration certificate.
How is operator identity authenticated?
Via four-digit PIN entry; up to 10 unique operator profiles can be stored onboard with individual access permissions.
