Introduction
1.1 Overview
This manual describes installation, operation and maintenance for
the Model 2120XL Trace Nitrogen in Argon Gas Analyzer. Section 1
describes the analyzer in general terms and provides additional safety
information pertinent to the proper operation of the instrument.
The Teledyne Model 2120XL Trace Nitrogen in Argon Gas
Analyzer is a robust analytical tool for measuring trace amounts of
nitrogen in argon. Using precise optical filtering, single line emission
characteristic of nitrogen is produced with an intensity proportional to
the nitrogen concentration.
The Model 2120XL has three user programmable analysis ranges
extending from 0-1 ppm to 0-100 ppm with corresponding analog output
signals that are proportional to the concentration on the selected range.
The nitrogen concentration is displayed on the front panel and the
analog output signals are available at the rear panel. Digital
communication is achieved with a standard RS-232 serial port.
The system is easy to operate with all controls and indicators
accessible from the front panel. Digital flow control, two adjustable
concentration alarms, system alarm, self-diagnostics are just a few of the
many features included on the standard Model 2120XL instrument.
1.2 Typical Applications
The Model 2120XL Trace Nitrogen in Argon Gas Analyzer is used
in a wide range of applications including:
 Air separation plants
 Argon Purification Plants
 Specialty Gas Laboratories
 Specialty Steel Manufacturing
 Gas Management/Monitoring Systems
