Analyzer Air; Carrier Gas; Sample; Hydrogen Gas - ABB PGC2000 Operation And Service Manual

1. Do not remove the tube caps, provided at the analyzer tubing ports to prevent deterioration of the
columns, until immediately before making each connection.
2. Use an anticorrosion material for the lines and fittings.
3. To ensure using proper size tubing and pipe, refer to the Outline and Mounting Dimensions
Diagram contained in the Data Package.
4. Use lines and fittings free of interior contamination from grease, oil or other substances. Before
connecting these lines, completely air-purge their interiors.
5. Carefully connect the lines so that there are no leaks from the connections. Leak check each
connection as described in the "Leak Check" paragraph.

Analyzer Air

The air supply is connected to the fitting marked Air In.

Carrier Gas

The carrier gas is connected to the fitting marked Carrier In.

Sample

The methods used for transporting the sample from the process stream to the analyzer or from the
calibration sample to the analyzer are critical to the operation of the analyzer. Refer to the system
drawings in the Data Package for specific sample system connections.

Hydrogen Gas

Hydrogen is highly explosive. Follow applicable safety precautions and use
extreme care in making connections.
It is the customer's responsibility to ensure that the hydrogen supply to the
analyzer does not exceed 100 psig (689 kPa, 6.89 bar) and that the customer's
pressure relieving devices are set to relieve at 200 psig (1380 kPa, 13.8 bar).
Failure to control the hydrogen pressure within these specifications may cause
loss of property and loss of life.
The analyzer uses hydrogen gas as a burner fuel with flame cell detectors (FID and FPD) and
sometimes uses it as a carrier gas. Verify that the hydrogen gas meets the criteria stated in the "Gas
Requirements" paragraph. Refer to the Data Package for specific connection information.

Vent

Typical analyzer vents are: Cell Vents, Backflush Vent, Sample Vent, and Housing Vent. All vents
must be at atmospheric pressure unless otherwise specified in the Data Package. The vent lines
should slope down from the analyzer so that condensation will not collect in the analyzer or cause
backpressure in the external tubing. Refer to the Data Package for specific connection information.
It is the customer's responsibility to set relief devices used to protect the analyzer and prevent
hazardous releases at a maximum pressure of 200 psig (1380 kPa, 13.8 bar).
