AGC NovaPRO 9000 Intrinsically Safe Online Gas Chromatograph

Overview

The AGC NovaPRO 9000 Intrinsically Safe Online Gas Chromatograph is an engineered solution for continuous, real-time compositional analysis of high-purity process gases in hazardous environments. Designed specifically for Zone 1 and Zone 2 classified areas per IEC 60079-0 and IEC 60079-2, the system implements pressurized enclosure protection (Ex pxb IIB+H2 T3 Gb) to ensure operational integrity under flammable hydrogen-rich atmospheres. Its core analytical architecture follows standardized gas chromatographic separation principles—employing temperature-programmed elution in multiple independently controlled column ovens, coupled with selective detection technologies including helium ionization (DID), flame ionization (FID), thermal conductivity (TCD), sulfur/phosphorus-specific (FPD), and photoionization (PID). The instrument delivers quantitative resolution across concentration ranges spanning parts-per-trillion (ppt) to percent-level—enabling compliance with ISO 8573-5 (compressed air purity), ASTM D7165 (hydrogen fuel quality), and ISO 14687-2:2019 (fuel cell grade hydrogen specifications).

Key Features

• Explosion-proof certified enclosure (Ex pxb IIB+H2 T3 Gb) with front-access safety interlocked door and integrated gas flow shutoff logic
• Dual-redundant temperature control architecture: up to four independent column ovens, each programmable from +5°C to 450°C with ramp precision of ±0.1°C/min
• High-stability carrier gas delivery system featuring mass flow and pressure control (0–700 kPa, 0–500 mL/min) with real-time feedback compensation
• 12-inch industrial-grade capacitive touchscreen interface running embedded Linux OS; supports multi-language UI and audit-trail-enabled operation logs
• Modular detector bay accommodating AGC-manufactured DID, FID, TCD, FPD, or PID detectors—each factory-calibrated and traceable to NIST standards
• Multi-port valve manifold (4-/6-/8-/10-position) constructed from stainless steel or Hastelloy C-276 for corrosion resistance in aggressive sample matrices (e.g., H₂S, Cl₂, HF)
• Integrated alarm hierarchy with configurable thresholds: component-specific concentration alarms, flow deviation alerts, temperature excursion warnings, and hardware fault diagnostics

Sample Compatibility & Compliance

The NovaPRO 9000 is validated for direct analysis of ultra-high-purity (UHP) hydrogen, natural gas, ethylene, propylene, and synthesis gas streams. It meets stringent requirements for fuel-grade hydrogen certification (ISO 14687-2, SAE J2719), semiconductor-grade nitrogen/argon purity verification (SEMI F57), and refinery off-gas monitoring per EPA Method 18. Sample introduction utilizes inert 1/8″ stainless steel or Hastelloy tubing with Swagelok® or VCR fittings, minimizing adsorption artifacts and ensuring long-term baseline stability. All wetted materials conform to ASTM A269/A270 standards. The system architecture supports GLP/GMP data integrity requirements through electronic signature-capable TrendVision PRO software, compliant with FDA 21 CFR Part 11 Annex 11 validation frameworks.

Software & Data Management

TrendVision PRO serves as the central supervisory platform for method development, remote diagnostics, and regulatory reporting. It enables full chromatographic method scripting—including multi-step temperature gradients, valve sequencing logic, and detector switching protocols. Raw chromatograms, trend plots, and DPM (defects per million) summary reports are auto-generated and exportable in CSV, PDF, and XML formats. Data archiving supports SQL-based historical databases with role-based access control, retention policy enforcement, and automated backup to network storage. Audit trails record all user actions—including method edits, calibration events, and alarm acknowledgments—with immutable timestamps and operator identifiers.

Applications

• Trace impurity profiling in proton-exchange membrane (PEM) fuel hydrogen (CO, CO₂, CH₄, O₂, N₂, H₂O at ppb levels)
• Continuous monitoring of hydrogen purity in chlor-alkali plants and ammonia synthesis loops
• Natural gas composition tracking (C₁–C₆ hydrocarbons, H₂S, CO₂, He, N₂) for custody transfer and calorific value calculation
• ppb-level CO and CO₂ quantification in polymer-grade ethylene and propylene feedstocks
• Residual solvent analysis in pharmaceutical purge gas streams per ICH Q3C guidelines
• Off-gas composition verification in catalytic reforming and hydrocracking units

FAQ

What certifications does the NovaPRO 9000 hold for hazardous area installation?
The system complies with IEC 60079-0 (general requirements) and IEC 60079-2 (pressurized enclosure protection), certified Ex pxb IIB+H2 T3 Gb for use in Zone 1 and Zone 2 locations.

Can the instrument operate unattended for extended periods?
Yes—designed for 24/7 operation with automatic leak detection, pressure decay monitoring, and scheduled self-diagnostic routines. Mean time between failures (MTBF) exceeds 12,000 hours under typical process conditions.

Is method transfer possible from laboratory GC systems?
Method portability is supported via standardized GC method import (ASTM E260-compliant syntax) and retention time alignment algorithms. Column geometry and temperature program parameters are mapped directly to NovaPRO hardware constraints.

How is calibration traceability maintained?
Each detector undergoes factory calibration using NIST-traceable certified gas standards. On-site calibration verification follows ISO/IEC 17025 procedures, with electronic calibration certificates stored within the TrendVision PRO audit log.

What cybersecurity measures are implemented?
The embedded OS includes TLS 1.2 encryption for remote connections, configurable firewall rules, disabled default accounts, and periodic security patch updates aligned with IEC 62443-3-3 Level 1 requirements.
