1.1 OVERVIEW
This manual describes the Trace Oxygen (TO2) Analyzer Module of Rosemount
Analytical's NGA 2000 Series of gas analysis components.
The TO2 Analyzer Module is designed to continuously determine the concentration of
trace oxygen in a flowing gaseous mixture. The concentration is expressed in partsper-million.
The TO2 Analyzer Module is configured as a shelf-mount module, designed to be
installed external from the platform on an associated shelf capable of holding two
modules side-by-side, with gas connections made from the rear. All electronics relative
to sample detection and conditioning are included in this module.
1.2 TYPICAL APPLICATIONS
The TO2 Analyzer Module has specific applications in the following areas:
Trace oxygen in product nitrogen and argon streams from air separation plants
Trace oxygen in inerting atmospheres for heat treat furnaces
Trace oxygen in glove-box applications
1.3 THEORY OF TECHNOLOGY
The TO2 Analyzer Module uses the coulometric principle of oxygen detection. This
technology is based on the fact that oxygen in the sample is reduced by an
electrochemical reaction. This reduction occurs at the cathode and results in the
generation of hydroxyl ions. These hydroxyl ions migrate to the anode where they are
oxidized to reform oxygen. The oxidation reaction generates four electrons which in
turn migrate to the anode to participate in the reduction reaction:
(Cathode Reaction)
O2 + 2 H2O + 4 e- → 4 OH
(Anode Reaction)
4 OH- → O2 + 2 H2O + 4 e
-
-
748374-E Rosemount Analytical September 2000
NGA 2000 Trace Oxygen Analyzer
1-1
NTRODUCTION
I
A polarizing voltage of approximately 1.3 VDC is applied between the anode and
cathode to drive the oxidation and reduction reactions. The resulting current flow
produced by the flow of electrons is directly proportional to the oxygen content in the
sample gas.
1.4 FEATURES
Among the features included in the TO2 Analyzer Module are:
• Quick start feature
• Electrolyte level alarm
• High oxygen protection circuit with alarm
• Sample flow indication.

2.1 UNPACKING
If the Trace Oxygen (TO2) Analyzer Module is received as a separate unit, carefully
examine the shipping carton and contents for signs of damage. Immediately notify the
shipping carrier if the carton or contents is damaged. Retain the carton and packing
material until all components associated with the TO2 Analyzer Module are
operational.
2.2 ASSEMBLY
Before installation of the TO2 Analyzer Module, electrolyte must be added to the
Sensor. Follow the procedure described below under section 2.2.1.
After addition of electrolyte, locate the analyzer module on an appropriate mounting
surface and connect the network cable to either the NETWORK 1 or NETWORK 2
connection on the Analyzer Module, and the NETWORK connection on the Platform
network I/O port. (See Figures 2-1 and 2-4.)
2.2.1 E
LECTROLYTE ADDITION
Before adding electrolyte to the Sensor, it is recommended to check the Sensor for
possible leakage caused by damage in shipment. To check the Sensor for leakage,
remove the top cover of the Analyzer Module and locate and remove the 5 mounting
screws which hold the Sensor Assembly (Sensor, flow meter, plumbing, inlet/outlet
fittings) to the module (see Figure 4-2). Be careful not to lose these screws as they
have metric threads. Carefully lift out the Sensor assembly and remove from the
analyzer module. Place on a flat surface and remove the black Sensor cover by
unscrewing counterclockwise.
Add distilled or deionized water to the Sensor to the maximum level indication on the
Sensor reservoir. Let Sensor stand for approximately 15 minutes and check for leaks
around the base of the reservoir, and at the seams and corners. If a leak is found,
contact the factory before proceeding. Drain the Sensor.
Fill the Sensor with one bottle of electrolyte supplied with the analyzer module. Use
the entire contents of the bottle.

NSTALLATION
I
Note:
Do not add water. The volume and concentration of the bottled electrolyte is
pre-measured.
Reinstall the black Sensor cover and carefully reinstall the Sensor Assembly inside the
Analyzer Module. Do not the tilt the Sensor Assembly excessively as electrolyte may
leak out.
2.3 LOCATION
(See Figure 2.2) The TO2 Analyzer Module comes standard with mounting ears for
easy installation on flat, horizontal surfaces. Install the TO2 Analyzer Module in a
clean, weather-proofed, vibration-free location free from extreme temperature
variations and moisture. For best results, install the instrument near the sample stream
to minimize sample transport time.
Operating ambient temperature is 0 °C to 45 °C (32 °F to 81 °F). Temperature change
should not exceed 10 °C (18 °F) per hour. The same temperature restrictions apply to
the location of the zero and span gas cylinders.
2.4 GASES
2.4.1 R
EQUIREMENTS
The TO2 Analyzer Module requires only a standard of accurately known composition
for use as a span gas. The span gas should be supplied from a cylinder equipped with
a clean, metallic diaphragm, two-stage regulator. A shutoff valve is recommended.
ALIBRATION GASES
C
The TO2 module does not require routine zero calibration. The zero is factory set and
does not experience routine drift. Over long periods of time, the zero may experience
minor drift. For low ppm range analyzers, you may wish to check the zero at one year
intervals. Oxygen-free nitrogen is recommended for use as zero gas. This gas is
certified to <0.5 ppm oxygen and can be improved by passing the zero gas through an
oxygen scrubber such as Millipore™ Waferpure or Semigas Nanochem® resin
purifiers. A mixture of trace oxygen in a background of nitrogen is recommended as
span gas. For maximum accuracy, the concentration of trace oxygen in the span gas
should be as high as possible for the range of measurement.

AMPLE
S
The sample must be clean and dry before entering the Analyzer Module. Sample
should be filtered for particulates down to two microns, and should have a dew point at
least 5 °C (13 °F) below the coldest expected ambient temperature.
RESSURE
P
Constant between 13.8 and 69 hPa - gauge (0.2 and 1.0 psig) sample inlet pressure
is recommended. If a needle valve is used upstream of the Analyzer Module to control
flow, the inlet pressure to the needle valve should not exceed 345 hPa (5 psig). A
constant sample flow rate between 1.0 to 3.0 SCFH (0.5 to 1.5 l/min) is recommended
for best results. The Analyzer Module must vent to atmosphere to avoid back
pressure influences on the oxygen reading.
2.4.2 C
ONNECTIONS
(See Figure 2-3. ) Connect inlet and outlet lines for sample to appropriately labeled
fittings on the rear panel. SAMPLE IN and SAMPLE OUT are 1/4-inch ferrule-type
compression fittings. Zero and span gases should be introduced at the SAMPLE IN
fitting at normal sample inlet flow rate.
Metallic tubing is recommended for the sample line. The use of plastic, Teflon, or
other non-metallic tubing can result in ambient oxygen permeation through the tubing
causing higher than expected reading. Exhaust tubing should be 1/4 inch (6.3 mm) or
larger, and can be metallic or non-metallic.

CAUTION: GAS OVERPRESSURE
At no time should sample, zero or span gas inlet pressure exceed 69 hPa gauge (1.0 psig). Damage to the Sensor may occur if this pressure level is
exceeded.
CAUTION: SAMPLE FLOW
Do not test the sample pressure by blocking the exhaust. When the pressure is
released the sudden surge of flow will spin the internal flowmeter off its
bearings and destroy it.
2.4.3 LEAK TEST
The TO2 Analyzer Module is completely tested at the factory for gas leakage. The
user is responsible for testing for leakage only at the inlet and outlet fittings on the rear
panel. Caution: Do not expose the Sensor to pressure in excess of 1.0 psig as
this may cause damage.

3.3 STARTUP PROCEDURE
Establish sample or zero gas flow through the analyzer module at a nominal flow rate
of 2 SCFH (1 l/min). Allow gas to flow for 15 to 30 seconds before applying power.
Apply power to the TO2 Analyzer Module.
Upon initial startup, the separate modules, Controller Board and network "self-install."
The display shows the progress of the automatic installation routine, together with a
button marked RE_INIT. If the initialization hangs up, pressing the RE_INIT button will
restart it, but will cause all the binding information to be erased. The Display will then
appear as above. For details on binding, please consult the Platform instruction
manual.
Establish that sample flow rate is within specifications (see the Specifications page in
this manual). Input security codes (see reference manual), calibrate, and begin routine
operation as following subsections indic ate.
3.4 QUICK START FEATURE
This analyzer module is equipped with a quick start feature which allows the sensor to
begin measuring low ppm oxygen faster. This feature can be used when the analyzer
is first turned on to decrease the time required for the sensor to reach equilibrium.
This function is most effective for gas sample measurements below 100 ppm. To
maintain sensor life, it is recommended that this feature be used no more than two
times in any 24 hour period.
Under the Basic Controls sub-menu, move the cursor to Initiate quick start! and press
the ↵ key. The unit will begin the quick start function imm ediately. This p rocedure will
last for approximately 45 seconds. The last measured value is held for the duration of
the procedure to prevent false reading fluctuations.
3.5 GAS SCALE FACTOR (GSF)
The Gas Scale Factor is used to correct for background gases other than nitrogen.
When the backgro u nd of the sam p le is oth e r t ha n ni tro ge n , th e d iff us io n rate of o xygen
into the sensor changes. By correcting for the background difference, the diffusion
change can be compensated in software. The GSF can be entered manually or
calculated automatically. Calculation of the GSF requires the user to enter the sample
gas composition. In most applications, the GSF is not required. However, some
backgrounds exhibit significantly different diffusion characteristics versus nitrogen
(such as helium or hydrogen) and the GSF may improve performance.
Under the Technical Level Configuration sub-menu, select Diagnostic menus... and
then select Analyzer Module Diagnostics…. In the Analyzer Module Diagnostics sub-
menu select Calibration Parameters.... In the Advanced/Expert Calibration sub-menu
select Gas Scale Factor.... To use the GSF, enter the volumetric percentages of each
component present in the sample gas. To view more background components, press

the MORE softkey. The total must add up to 100 or a new factor will not be computed.
If you have a background component which is not shown in this menu, please consult
the factory for assistance.
Once you have entered all the background composition information, move the cursor
to Compute new adjusted gas scale factor! and press the ↵ key and the analyzer
module will automatically calculate the new gas scale factor.
3.6 CALIBRATION
The TO2 analyzer module is fully factory calibrated using certified gas standards prior
to shipment. If the analyzer is operated within its specified operating conditions, no
calibration is required. The zero calibration is very stable and does not require
checking more than once a year. Depending upon the nature of your application, it
may be beneficial to verify the span calibration of the analyzer module every 3-4
months. The following procedure illustrates how to initiate a zero/span calibration.
Under the Expert Controls sub-menu select Expert Analyzer Controls and
Measurement…, set the Range Number to the range that will be used during sample
analysis. Return to the Main Menu by pressing the HOME softkey.
Introduce zero gas into the SAMPLE INLET, and, after a stable reading is reached, do
the following:
1. Move the cursor to Technical Level Configuration... and enter. Select Diagnostic
Menus…, then Analyzer Module Diagnostics…, and then Calibration parameters...
and enter.
2. Select the User zero calibration... to enter the User zero calibration menu.
Note:
Before proceeding any further, be sure that the zero value is stable and valid.
The zero may take 24 hours or longer to achieve stable zero for the low ranges.
3. Move the cursor to the Press the select key for user zero calibration now!
4. Press the ↵ key. The new zero calibration will now be entered.
5. Press the ← key to return to the previous menu.
6. Introduce a suitable span gas into the SAMPLE INLET and allow reading to
stabilize. Move the cursor to the User span calibration... line and press the ↵ key.

If you are unable to calibrate the module for some reason, see the NGA Reference
manual for a list of possible causes and solutions. The most likely cause is the use of
incorrect span gases.
3.7 ROUTINE OPERATION
The TO2 Analyzer Module is designed to analyze the sample stream continuously.
Normally, it is never powered off except for servicing or for a prolonged shutdown.
Maximum permissible interval between calibration checks depends on the analytical
accuracy required, and therefore cannot be specified. Initially, the instrument should
be checked at least once every 3-4 months. This practice should continue until
experience indicates that some other interval is more appropriate.
For details as to the general operation of the NGA analyzer module software, and the
use of IO modules with the TO2 module, see the Platform Components manual.

4.1 OVERVIEW
CAUTION: QUALIFIED PERSONNEL
This equipment should not be adjusted or repaired by anyone except properly
qualified service personnel.
WARNING: PARTS INTEGRITY
Tampering with or unauthorized substitution of components may adversely
affect safety of this product. Use only factory-approved components for repair.
The TO2 Analyzer Module requires very little maintenance during normal operation.
The sensor in the TO2 utilizes a liquid e lectrolyte. When me asuring dry gases, it may
be necessary to replenish the liquid by adding distilled or deionized water.
The sensor is designed to hold at least 100 cc of electrolyte. Typically, bone dry
sample gas can extract approximately 5-10 cc of water per month from the sensor. It
is recommended to check the electrolyte level every 3-4 months to assure that the
electrolyte level is within the acceptable operating limits as indicated by the label on
the reservoir section of the sensor.
The TO2 analyzer module is equipped with a low electrolyte alarm which indicates
when replenishment of the sensor is required. Please refer to the Platform manual for
details on configuring alarms.

fuses in the Analyzer Module.
4.3 ELECTROLYTE REPLACEMENT
Before replacing the electrolyte, be sure to turn off and disconnect all gas connections
to the analyzer module. Turn off or disconnect the power to the analyzer module.
To replace the Sensor electrolyte, remove the Analyzer Module from its mounting
location and place on a sturdy work surface. Be careful not to tilt the module from its
horizontal position as the Sensor contains liqu id that can spill. Remove the cover of
the Analyzer Module and locate the 5 mounting screws that hold the Sensor Assembly
onto the Analyzer Module chassis (see Figure 4-1). Remove the 5 screws and retain.
Do not lose the screws - they have metric threads.
Disconnect the Sensor signal connector (J5) and the Flow Sensor connector (J6) from
the power board. Remove the complete Sensor Assembly from the Analyzer Module.
Remove the black sensor cover and invert the Sensor Assembly over a suitable
receptacle. Flush the Sensor twice with deionized water. Dispose of the discarded
electrolyte and rinse water in accordance with National, Federal, State and Local
regulations.
Refill the Sensor with electrolyte as instructed in Section 2.2.1. Reinstall th e Sensor
Assembly and reconnect J5 and J6 to the power board.

4.6 PRINTED CIRCUIT BOARDS
All three printed circuit boards can be replaced, if necessary. Refer to Figure 1-2 for
location of the Power, Network and Computer Boards.
To remove any PCB, disconnect the associated cables first. Tag each connector and
its location before disconnecting any wiring. This helps in reassembly. The Power
board and Computer board are located on a common bracket.
4.7 TROUBLESHOOTING
The following provides a short list of common troubleshooting tips. Additional
information is contained in the Platform Manual.
HE
T
TO2
Prior to conducting any changes to the system, try running a quick start sequence (see
section 3.4) to see if the oxygen reading goes lower. If the reading does decrease, the
sensor has not been allowed sufficient time to consume the dissolved oxygen in the
electrolyte. If the reading continues to read high a leak may exist in the sample lines.
The number one problem associated with trace oxygen analyzer installation is the
occurrence of leaks in your sample plumbing. If the oxygen reading will not come
down to ppm levels or is reading higher than expected, the sample plumbing prior to
the instrument may have a leak. A quick check can be conducted by observing the
oxygen reading at two different flow levels; 0.5 and 2.0 scfh. If the oxygen reading
drops significantly when the flow is increased from 0.5 to 2.0 scfh, this is a good
indication that a leak exists.
To check for leaks prior to the sensor, disconnect the Analyzer Module and cap the
inlet line. Pressurize the inlet line to 5 - 10 psig and check all connections with a
soapy solution (SNOOP®) to identify leaks.
ANALYZER FAILS TO PURGE DOWN TO PPM LEVELS
.
WARNING: SENSOR DAMAGE
Do not pressure check the sample line with the sensor connected. Overpressurization of the sensor can result in damage.
HE
T
TO2
Check to make sure that your vent line is not blocked. If you see a rise in reading with
an increase in flow, you may be over-pressurizing the sensor due to a blocked vent.
Since the sensor is a partial pressure measuring device, an increase in sample
pressure will cause an increa se in reading. If the reading drops with increased flow,
conduct the leak check outlined in the troubleshooting tip above.

Check to see that the electrolyte level is within the limits indicated on the reservoir.
Add distilled water as required. If the level is within limits, the electrolyte may have
been contaminated. Refer to section 4.2 above for proper procedure to replace
electrolyte. If replacement of electrolyte does not improve the performance of the
sensor, the sensor may have been damaged due to over-pressurization or poisoning.
Sensor replacement may be required as described in section 4.3 above.
