On-Line Process Conditions – Analyzer Purged with Nitrogen:
Process OPL: NH
3
and H
2
O
Analyzer Purge: N
2
In this Absorption Spectra view, the Process H
2
O
absorption peak can be seen at approximate
peak center position (PCP) 167. This absorption
peak is Process H
2
O as there is no reference gas
H
2
O in the N
2
analyzer purge gas.
There is also approximate 20 ppm NH
3
(@ approx PCP
120) absorption in this spectra based on 72.6 cm OPL,
ambient temperature and ambient pressure.
Process OPL: Zero NH
3
+ ~2% H
2
O Air
Analyzer Purge: N
2
In this Absorption Spectra view, the large process
H
2
O absorption peak can be seen at
approximate peak center position (PCP) 167.
There is no NH
3
absorption in the spectra .
Process OPL: ~20 ppm NH
3
+ Zero H
2
O
Analyzer Purge: N
2
In this Absorption Spectra view, there is practically
zero process H
2
O absorbtion peak in the approximate
peak center position (PCP) 167 region.
There is approximate 20 ppm NH
3
(@ approx PCP
~120) absorption in this spectra based on 72.6 cm
OPL, ambient temperature and ambient pressure.

On-Line Process Conditions – Analyzer Purged with Nitrogen:
Process OPL: Measured and Reference gas
(NH3 and H2O)
Analyzer Purge: N2
In this Absorption Spectra view, the reference gas
(H2O) absorption peak can be seen at approximate
peak center position (PCP) 167. This absorption
peak is from the reference gas contained in the
process stream ( H2O) as there is no reference gas
(H2O) in the analyzer purge gas.
There is also approximate 20ppm NH3 (measured
gas) (@ approx PCP 120) absorption in this spectra
based on 72.6cm OPL, ambient temperature and
ambient pressure.
Process OPL: Zero Measured Gas (NH3) + ~2%
H2O (Reference Gas)
Analyzer Purge: N2
In this Absorption Spectra view, the large reference
gas (H2O) absorption peak can be seen at
approximate peak center position (PCP) 167.
There is no measured gas (NH3) absorption in the
process .
Process OPL: ~20ppm Measured Gas (NH3) +
Zero Reference Gas (H2O)
Analyzer Purge: N2
In this Absorption Spectra view, there is practically
zero reference gas contained in the process stream.
No absorption from H2O at the approximate peak
center position (PCP) 167 region.
There is approximate 20ppm measured gas (NH3)
(@ approx PCP ~120) absorption in this spectra
based on 72.6cm OPL, ambient temperature and
ambient pressure.
