The averaged output can be formatted to be accepted by a 3rd party gas

accounting software system, allowing automatic downloads

of the analysis data. Analysis done on site is valuable because:

– Transportation of DOT regulated gas cylinders is avoided

– Time and cost of subsequent laboratory analysis

– Problems with sample handling

– Economic solution for gas quality measurement when the

gas volumes are too low to justify on-line chromatography

Standard features

Modular design includes

– Portable GC interface allows user analysis customization

– Modular software – application based plug in software modules

– Manifold module (internal tubing now replaced by manifold)

– Analysis sections contain stream selection solenoids,

temperature and pressure regulation, 32 bit digital detector

electronics, replaceable column / valve modules and a low

power 32 bit digital controller, using Windows CE® (internal

to GC unit)

– Microsoft® Windows® based man-machine interface

software (PCCU)

– USB MMI port connectivity

– Ethernet connectivity

– Lithium battery-backed RAM

– Two remote serial digital communications ports; one local port

– Comprehensive diagnostics and wizards available to users

– Audit-quality historical data; date and time stamped

– Operational fault/warn alarms available

– Detectors – constant temperature, glass encapsulated

thermister beads for rugged service and long life; will not

burn out on loss of carrier

– 10 port valves have no moving metal parts in each

analysis unit

– Low utility usage – low-power, low-carrier, no instrument air

required

– On demand or scheduled automatic calibration and

diagnostics

• Calculation packages (eg, Hydrocarbon Dew

point via SRK and Peng-Robinson, including: 4

pressures and the Cricondentherm)

• Integral gas flow tube calculations (e.g. Orifice or

turbine meter calculations)

• SD memory cards for raw chromatogram storage

• Feed-Through heater for colder operations or

high dew point gas sampling
