TGA100A Trace Gas Analyzer Overview
OV1. System Components
Figure OV1-1 illustrates the main system components needed to operate the
TGA100A. These system components include:
•
TGA100A Analyzer: The analyzer optics and electronics, mounted in an
insulated fiberglass enclosure.
•
Computer: A user-supplied computer to display data and set parameters.
•
Optional Datalogger (CR5000 shown): Receives concentration data from
the TGA100A through the SDM interface cable.
•
Sample Intake (15838 shown): Filters the air sample and sets its flow rate.
•
Sample pump (RB0021-L shown): Pulls the air sample and reference gas
through the analyzer at low pressure.
•
Suction hose (7123 shown): Connects the analyzer to the sample pump.
Supplied with RB0021 sample pump.
•
Reference gas: tank of reference gas, with pressure regulator (supplied by
user).
•
Reference gas connection (15837 shown): Flow meter, needle valve, and
tubing to connect the reference gas to the analyzer.
