ABB NGC8206 is an online gas chromatograph built specifically for the natural gas industry, representing the third‑generation technological flagship of ABB’s Totalflow series.

As a fully functional chromatograph transmitter, it enables online gas analysis and heating value calculation in pipeline installations where traditional GC systems are either impractical or cost‑prohibitive. The unit uses revolutionary manifold technology in place of conventional internal tubing, achieving an ultra‑compact footprint of just 1.1 cubic feet — more space‑efficient than most multivariable transmitters.

The NGC8206 integrates a 32‑bit Windows CE controller, dual electronic carrier gas pressure regulators, a sensor‑controlled constant‑temperature oven, and low‑noise electronics, delivering exceptional sensitivity with calibration intervals lasting several months.

It remotely analyzes natural gas components from N₂ up to C₆+, with optional H₂S separation, and outputs analysis data in formats compatible with nearly all third‑party software. Fast analysis and automatic adjustment make installation and maintenance extremely simple; even operators with minimal GC experience can use it reliably, greatly lowering operational costs and technical barriers.

The real strength of the ABB NGC8206 lies in its revolutionary design and outstanding performance.

Its compact, low‑power architecture stands out: the unit consumes less than 7 watts, enabling continuous operation without excessive energy cost. This makes it ideal for space‑constrained pipeline installations and offers flexible deployment across the entire natural gas supply chain.

Modular maintenance is another major advantage.

All hardware and software are designed as easily replaceable electromechanical modules — including the faceplate, analysis module, manifold, and flow selection solenoid valves — allowing quick swap‑out without specialized skills. This drastically reduces maintenance time and cost. The dual 10‑port valves use no moving metal parts, supporting long‑term reliability and stability.

Advanced detection technology ensures high‑performance analysis.

The system uses exponential response factors instead of traditional linear calibration, delivering superior linearity via multi‑point exponential curve fitting. Its glass‑encapsulated bead thermistor detector withstands harsh environments, offers long service life, and will not burn out even if carrier gas is lost. Fully automatic self‑start cycles stabilize oven temperature, verify module health, and set column and valve timing automatically, ensuring consistent and accurate analysis.

ABB NGC8206 serves across the full natural gas supply chain, from upstream production to downstream distribution.

At natural gas wellheads, it provides real‑time produced‑gas composition analysis, delivering critical data for production optimization and reserve evaluation. Its compact size and low power make it ideal for remote well sites with limited power and space.

In natural gas transmission pipelines, the NGC8206 acts as a custody‑transfer quality chromatograph, accurately measuring composition, heating value, density, and compressibility. These measurements are essential for fiscal metering, energy calculation, and pipeline operation optimization. It integrates seamlessly with SCADA systems and flow computers for real‑time data transmission, ensuring measurement accuracy and trade fairness.

It is also widely used in urban gas distribution networks at gate stations, pressure‑regulation stations, and large industrial user connections to monitor gas quality and ensure compliance with standards. A portable version supports temporary monitoring, mobile inspection vehicles, and emergency response.

The unit also plays a key role in LNG terminals, storage facilities, and natural gas power plants for quality control and process optimization.

Before installing the ABB NGC8206, confirm the environment meets operational requirements: adequate space, stable power, and a reliable carrier gas supply.

Avoid strong vibration and electromagnetic interference. Pipeline connections must follow specifications to ensure representative and stable sample flow.

For cold regions, install cold weather accessories in advance to guarantee performance at low temperatures. Power wiring must meet explosion‑proof requirements, and communication cables should be routed for stable, secure signal transmission.

Maintenance of the NGC8206 is simple and efficient thanks to its modular design.

Regularly check carrier gas pressure and consumption to ensure stable supply.

Cleaning and calibration of the analysis module are only required at intervals of several months.

The software can be updated and diagnosed remotely via PCCU 32, allowing early detection and resolution of potential issues. For long‑term operation, regularly back up historical data and configuration parameters to prevent accidental loss.

Comprehensive built‑in diagnostics and operational guides help technicians quickly identify and resolve problems.
