Trace Nitrogen in Argon Analyzer Introduction
Introduction
1.1 Overview
This manual describes installation, operation and maintenance for
the Model 2120 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 2120 Trace Nitrogen in Argon Gas Analyzer
is a robust analytical tool for measuring trace amounts of nitrogen in
argon. There are two separate instruments in the 2120 series to cover
different analytical ranges:
Series 2120-A (115 V) 0-2 and 0-20 ppm
Series 2120-B (115 V) 0-20 and 0-200 ppm
For enhanced sensitivity extending to 10 ppb, the Model 2120
employs a photomultiplier tube (PMT) to optically distinguish the
spectrum generated from an ionized sample gas oscillating at a specific
frequency in the analytical cell. Using precise optical filtering, single
line emission characteristic of nitrogen is produced with an intensity
proportional to the nitrogen concentration. The nitrogen concentration is
displayed on the front panel display meter and an analog output signal is
available at the rear panel.
The system is easy to operate with all controls and indicators
mounted on the front panel. Overrange protection alarm, low flow
alarm, convenient test jack panel are just a few of the many features
included on the standard Model 2120 instrument.
1.2 Typical Applications
The Model 2120 Trace Nitrogen in Argon Gas Analyzer is used in
a wide range of applications including:
• Air separation plants
• Argon Purification Plants
