Carrier Gas and Calibration Gas Connections
The following procedures describe the steps for connecting the external Carrier Gas and
Calibration Gas lines from the respective regulators to the Feed-Through Assembly on
the NGC. They are applicable for both a Meter Run and Cold Weather Enclosure
installation.
A. Materials
•
Installed Carrier Gas Pressure Regulator
•
1/16” SST Chromatography Grade Transport Tubing (Amount to be determined
by technician based on distance from Carrier Gas Bottle Regulator to Sample
Input Filter).
•
Installed Calibration Gas Pressure Regulator
•
1/16” SST Chromatography Grade Transport Tubing (Amount to be determined
by technician based on distance from Calibration Gas Bottle Regulator to Sample
Input Filter).
•
4 ea. 1/16” Ferrule and Nut
•
2 ea. ¼” NPT to 1/16” Reducer or other size as determined from
Carrier/Calibration Gas Regulator.
NOTE:
These instructions assume that the regulators and gas bottles have
previously been installed.
B. Instructions
1)
Locate Carrier Gas Input Port (CAR) on NGC Feed-Through Assembly (see
Figure 34).
2)
Locate ¼” Low Pressure Output fitting on installed Pressure Regulator.
3)
Measure and cut 1/16” SST Tubing to required length.
