Standard features

Modular design includes

• Modular software – application based plug in software

modules

• Manifold module (internal tubing now replaced by manifold)

• Analysis section contains stream selection solenoids,

pressure regulation, 32 bit digital detector electronics and

a dual-train chromatograph in a single, replaceable module

• 32 bit digital, low-power controlling electronics, using

Windows CE® (internal to GC unit)

• On board digital ¼ VGA display with multiple screen access

• Microsoft® Windows® based man-machine interface

software (PCCU 32)

port

• Comprehensive diagnostics and wizards available to users

• Three-level security for user access control

• Audit-quality historical data; date and time stamped

• Auto-start cycle automatically:

- Stabilizes oven temperature

- Confirms modules’ functions

- Validates/calibrates

- Returns to pipeline streams

• Operational alarms and events, time, and data stamped

in a log

Maintenance

The NGC8207 was designed from the ground up to be

maintained by personnel with little or no prior knowledge

of gas chromatography.

Both hardware and software are designed to provide low

maintenance through easily replaceable electro-mechanical

modules such as:

• NGC termination panel

• NGC analytical module, an easily removable chromatograph

subassembly, containing:

- NGC manifold

- Stream selector solenoid valves

- GC module

- Dual electronic carrier pressure regulator valves

- Chromatograph pilot valve

- NGC analytical processor

• NGC feed-through (heater optional)

• Sample conditioning module (SCM)

• NGC controller, (32 bit processor)

• NGC ¼ VGA display (optional)

Specifications

• Designed for pipeline-quality natural gas

• Environmental temperature

• Four stream capability; Manual calibration required

with 4 sample streams

• Single auto calibration stream and 3 sample streams,

or 2 auto calibration streams and 2 sample streams
