AGC NovaPRO9000 High-Purity Hydrogen Online Explosion-Proof Gas Chromatograph

Overview

The AGC NovaPRO9000 High-Purity Hydrogen Online Explosion-Proof Gas Chromatograph is a purpose-engineered analytical platform designed for continuous, real-time impurity monitoring in hydrogen production, purification, and distribution systems—particularly where safety-critical environments demand certified hazardous-area operation. Utilizing gas chromatography separation coupled with helium discharge ionization detection (DID), the NovaPRO9000 achieves sub-ppb detection sensitivity for permanent gases (e.g., O₂, N₂, CH₄, CO, CO₂, H₂O, Ar, Ne) and hydrocarbon impurities across %, ppm, and ppb concentration ranges. Its core architecture adheres to the principles of process analytical technology (PAT), delivering trace-level quantification with high reproducibility (±0.1% RSD) under unattended, 24/7 industrial operation. The system complies with EN 60079-0 and EN 60079-13 for pressurized enclosure (Ex p) protection, enabling direct installation in Zone 1 and Zone 2 classified areas per ATEX Directive 2014/34/EU (certified by BVS 06 ATEX E 088). Unlike general-purpose laboratory GCs, the NovaPRO9000 integrates hardware, firmware, and software into a single validated process instrument—engineered for long-term stability in ambient temperatures from –10 °C to +50 °C and compatible with integration into DCS, SIS, or MES architectures via industry-standard protocols.

Key Features

• Explosion-proof enclosure with certified Ex p (pressurized) protection per EN 60079-13; suitable for Zone 1/Zone 2 installations without external purge cabinets
• Independent per-column temperature-controlled oven—uniquely enabling simultaneous optimization of multiple column chemistries (packed, micro-packed, or capillary) within a single chassis
• Helium discharge ionization detector (DID) with 1 ppb detection limit for inert and reactive gases; fully manufactured in-house by AGC for traceability and service continuity
• Electronically controlled pneumatic (EPC) and electronic flow control (EFC) modules ensuring precise carrier and makeup gas regulation
• Industrial-grade 10″ capacitive touchscreen HMI with embedded Windows OS and AGC TrendVision PRO workstation software—operable without external PC or network dependency
• Modular valve manifold using Vici Valco® rotary valves (4-, 6-, 8-, or 10-port configurations) and Swagelok®/VCR stainless-steel fittings; optional Hastelloy® wetted parts for corrosive sample streams
• Integrated diagnostics including gas flow alarms, temperature zone monitoring, power isolation, and automatic shutdown on critical fault conditions
• Compact footprint (900 × 600 × 400 mm; 49 kg) with wall-mount or floor-stand options; powder-coated low-carbon steel chassis compliant with BS6496/BS6497 durability standards

Sample Compatibility & Compliance

The NovaPRO9000 is optimized for high-purity hydrogen matrices—including fuel-grade hydrogen (ISO 8573-8, ASTM D7652, SAE J2719), PEM electrolyzer output, and refinery purge streams. It supports single- or dual-channel sampling configurations with programmable sequence control for automated calibration gas introduction, zero-air validation, and multi-point standardization. All wetted materials meet ASTM F1193 for high-purity gas service, and the DID detector’s helium-based ionization mechanism eliminates carbon contamination risks inherent in FID-based systems. Regulatory alignment includes CE marking, ATEX certification (BVS 06 ATEX E 088), and ISO 9001:2015 manufacturing quality assurance. For pharmaceutical or regulated hydrogen applications, the system supports 21 CFR Part 11-compliant audit trails when deployed with TrendVision PRO’s optional electronic signature and user-role management module.

Software & Data Management

TrendVision PRO is a deterministic, real-time chromatographic control and reporting engine built on an embedded industrial computer with 24-bit ADC resolution. It executes fully digital temperature and flow control, generates DPM (Digital Process Monitoring) trend lines, chromatograms, and component-specific time-series plots, and exports data via 4–20 mA analog outputs, Modbus TCP/RTU, Profibus DP, RS232/RS485, and Ethernet/IP. Calibration curves are stored as independent methods with multi-level bracketing (single-point, two-point, or multi-point), and peak integration follows IUPAC-recommended baseline algorithms with configurable retention time windows. Alarm logic includes configurable high/low limits per component, relay-triggered shutdown sequences, and visual status indicators on the HMI. File management supports auto-folder creation, pre-load chromatogram preview, batch report generation (PDF/CSV), and secure remote diagnostics via encrypted HTTPS tunneling—enabling Tier-2 technical support without exposing internal network infrastructure.

Applications

• Real-time monitoring of hydrogen purity per ISO 14687-2:2019 for fuel cell vehicle refueling stations
• Impurity verification in green hydrogen production (electrolysis effluent analysis)
• Quality assurance of hydrogen used in semiconductor annealing and CVD processes
• Leak detection and purity verification in hydrogen storage and pipeline transmission networks
• Process optimization in ammonia synthesis and methanol production feed gas streams
• Compliance testing for ASTM D7652 (hydrogen purity by GC-DID) and ISO 8573-8 (gas purity classes)

FAQ

What safety certifications does the NovaPRO9000 hold for hazardous area installation?
It carries ATEX certification (BVS 06 ATEX E 088) under EN 60079-0 and EN 60079-13 for pressurized enclosure (Ex p) protection, permitting direct deployment in Zone 1 and Zone 2 classified locations.
Can the system analyze both permanent gases and hydrocarbons in the same run?
Yes—through method-defined column switching and detector selection; the independent column oven allows concurrent use of molecular sieve and PLOT columns with DID/FID hybrid detection if configured.
Is remote software update and calibration verification supported?
TrendVision PRO includes secure over-the-air (OTA) firmware updates and automated performance qualification (PQ) routines that verify detector response, retention time stability, and integration accuracy against reference standards.
What maintenance intervals are recommended for the DID detector and pneumatic system?
Under typical hydrogen service, the DID requires no consumables; routine verification every 90 days is advised. Vici Valco® valves are rated for >1 million cycles, and Swagelok® fittings require torque verification only during initial commissioning or after mechanical shock.
Does the system support integration with DeltaV, Emerson DCS, or Siemens PCS7?
Yes—via native Modbus TCP, OPC UA (optional), or hardwired 4–20 mA with HART, enabling bidirectional setpoint control, alarm forwarding, and live chromatogram streaming to central control rooms.
