ABB Gas Chromatography Instrument Product Introduction:
The NGC (Gas Chromatograph) can perform online gas analysis and calorific value calculation in situations where current chromatography technology is impractical or financially unfeasible. It is a true chromatography transmitter, and when installed in pipelines, it occupies less space than most multi-variable transmitters. Its features of rapid analysis and automatic adjustment make installation and maintenance very simple. The built-in 32-bit digital controller, dual electronic carrier gas pressure regulators, sensor-equipped constant temperature furnace, and low-noise electronic technology provide it with unparalleled sensitivity and a calibration interval of several months. The revolutionary new GC is Totalflow’s third-generation product. Its highly integrated multi-tube technology originated from Model 8000.
Standard features of the ABB gas chromatograph:
• The combined design includes:
Integrated software – Application-based plug-in software modules
Multi-pipe module (The multi-pipes have now replaced the internal pipeline connections)
The analysis section includes the flow path selection solenoid valve, pressure regulation, 32-bit digital detector electronic component, and a replaceable package.
A module with dual-channel parallel chromatography.
32-bit digital, low-power control electronic components, using Windows CE® (internally to the GC unit)
Human-machine interface software based on Microsoft® Windows® 2000 or NT (PCCU 32)
• Lithium battery – Supports RAM
• 2 个远程串行数字通信端口； 1 个本地端口
Provide users with abundant diagnostic functions and useful guides
A three-level security code is used to protect user access control.
Historical data on audit quality; the date and time are recorded.
• Fully automatic self-starting cycle:
Maintain stable furnace temperature
Confirm the functions of the module
Set the operation time of the column valve
Search for various components of natural gas (in the future)
Set the carrier gas pressure
Determine the composition of each component of natural gas
Confirmation/Calibration
Return to the pipeline flow path
Useful operational alerts for each analysis cycle
• Detector – Glass-sealed spherical thermistor, suitable for harsh environments and with long service life.
In the case of insufficient gas supply, it will not burn out.
• Double 10-way valve, with no moving metal parts.
• Low utilization of public services – Low energy consumption, low consumption of carrier gas, no need for instrument air
• Automatic verification and diagnosis can be set.
NGC 8206 was designed with the consideration that the product could be maintained by personnel who have little or no knowledge of gas chromatographs. All
The hardware and software have been designed as easily replaceable electronic mechanical modules to reduce maintenance, for example:
• NGC Terminal Faceplate
• NGC analysis module, an easily detachable chromatographic sub-component, including NGC multi-tube, flow path selection solenoid valve, and GC valve assembly.
