1.1 O
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 parts-per-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-byside, with gas connections made from the rear. All electronics relative to sample detection
and conditioning are included in this module.
1.2 T
The TO2 Analyzer Module has specific applications in the following areas:
VERVIEW
YPICAL APPLICATIONS
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 T
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:
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.
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 U
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 A
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
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.
NPACKING
SSEMBLY
LECTROLYTE ADDITION
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.

Note
Do not add water. The volume and concentration of the bottled electrolyte is premeasured.
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 L
(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, weatherproofed, 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 G
2.4.1 R
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 recommen ded.
Calibration Gases
OCATION
ASES
EQUIREMENTS
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™ W aferpure or Semigas Nanochem® re sin 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.

Sample
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.
°
Pressure
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
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 samp le line. The use of plastic, Teflon, or other nonmetallic tubing can resu lt in ambient oxygen permeation throu gh the tubing causing h igher
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 L
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.

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 ha ngs 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 indicate.
3.4 Q
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 re ach e quilibrium . This fu nction is
most effective for gas sample measurements below 100 ppm. To maintain sensor life, it is
recommended that this feature be us ed no more than two times in any 24 hour period.
TARTUP PROCEDURE
UICK START FEATURE
Under the Basic Controls sub-menu, move the cursor to
key. The unit will begin the quick start function immediately. This procedure 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 G
The Gas Scale Factor is used to correct for background gases other than nitrogen. When
the background of the sample is other than nitrogen, the diffusion rate of oxygen 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.

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

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.
3.8 A
NGA analyzer modules continuously monitor a number of internal parameters. It is possible
to make the analyzer generate certain kinds of alarm indications if these parameters' values
exceed or reduce below specified levels. The general alarm variable will have its value
changed if an alarm occurs. See the NGA Reference manual for further details.

WARNING: PARTS INTEGRITY
Tampering with or unauthorized substitution of components may adversely

The TO2 Analyzer Module requires very little maintenance during normal operation.
The sensor in the TO2 utilizes a liquid e lectrolyte. When measuring 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.
CAUTION: REFILLING SENSOR
When refilling the sensor, only use distilled or deionized water. Do not use
electrolyte or tap water as they can cause damage to the sensor. Take care not
to overfill.

If the electrolyte alarm is activated but the sensor shows sufficient electrolyte, the electrolyte
may have been contaminated by substances present in the sample which are chemically
incompatible with the sensor or electrolyte. If this should occur, the electrolyte must be
drained and replaced with fresh electrolyte.
Refer to section 4.3 for the proper procedure for replacing electrolyte.
Several other components may require replacement. These are discussed in the following
sections.

The following provides a short list of common troubleshooting tips. Additional information is
contained in the Platform Manual.
The TO2 analyzer fails to purge down to ppm levels.
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.
RINTED CIRCUIT BOARDS
ROUBLESHOOTING
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.
WARNING: SENSOR DAMAGE
Do not pressure check the sample line with the sensor connected. Overpressurization of the sensor can result in damage.
The TO2 analyzer exhibits flow sensitivity.
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 pressu re will cause an
increase in reading. If the reading drops with increased flow, conduct the leak check
outlined in the troubleshooting tip above.

The TO2 analyzer gives erratic and very insensitive readings.
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.
