TERMS USED IN THIS INSTRUCTION MANUAL

Instruction Manual
HASXEE-IM-HS
10/2012
Explosive Gas(es)
Flammable Gases and gas mixtures in a mix­ture with air within the explosive limits.
Flammable Gas(es)
Gases and gas mixtures are assigned to be ammable if they might become ignitable
when in a mixture with air.
Infallible Containment
This term is derived from the standards of explosion protection especially from the re­quirements for pressurized housings: thus an
infallible containment can be characterized by no intended leakage out of the gas paths enabling gas to enter the inner compartment
of the analyzer housing.
Intrinsically Safe Cell (IS Cell)
Cells supplied with an intrinsically safe power
signal, approved by a Test Institute, to operate
with explosive gases. The design ensures the IS cells remains safe
even in case of failure and explosive gases are not ignited.
Protection Class IP66 / NEMA 4X
Both terms are used to specify conditions for
equipment to be installed outdoor.
IP stands for Ingress Protection, the rst num-
ber species protection against solid objects
(6. = dust tight) while the second number
species the degree of protection against
liquids (.6 = heavy seas). NEMA stands for National Electrical Manuf-
acturers Association. 4X species a degree of protection to personnel against incidental contact with the enclosed equipment; to pro­vide a degree of protection against falling dirt,
rain, sleet, snow, windblown dust, splashing
water, and hose-directed water; and that will
be undamaged by the external formation of
ice on the enclosure
Upper Explosion Limit (UEL)
Volume ratio of ammable gas in air above
which an explosive gas atmosphere will not
be formed: the mixture of gas and air is too rich in fuel (decient in oxygen) to burn.
Lower Explosion Limit (LEL)
Volume ratio of ammable gas in air below
which an explosive gas atmosphere will not
be formed: the mixture of gas and air lacks sufcient fuel (gas) to burn.
NAMUR
NAMUR is an international user association of automation technology in process industries. This organisation has issued experience reports and working documents, called re­commendations (NE) and worksheets (NA).

CONNECTING UNITS FOR PERMANENT INSTALLATION
Safety Instructions
S
Wall-mounted units have no power switch and are operational when connected to a power supply . The operating company is therefore required
to have a power switch or circuit breaker (as per IEC 60947-1/-3) available
on the premises. This must be installed near the unit, easily accessible to operators and labelled as a power cut-off for the analyzer.
HAZARD FROM WRONG SUPPLY VOLTAGE
Ensure that the local power voltage where the unit is to be installed, corresponds to the unit’s nominal voltage as given on the name plate label.
ADDITIONAL NOTES FOR UNITS WITH SCREW-TYPE TERMINALS
Cables for external data processing must be double-insulated against mains power.
If this is not possible, cables must be laid in such a way as to guarantee a clearance of at least 5 mm from power cables. This clearance must be permanently secured (e.g. with cable ties).

General Operating Notes
GENERAL OPERATING NOTES
EXPLOSION HAZARD
Exhaust gases may contain hydrocarbons and other toxic gases such as carbon monoxide. Carbon monoxide is toxic.
Faulty gas connections may lead to explosion and death. Ensure that all gas connections are connected as labelled and airtight.
The unit must be installed in a clean and dry area protected from strong vibrations and
frost
.
The unit must not be exposed to direct sunlight and sources of heat. Admissable ambient temperatures (see technical details) must be adhered to.
Gas inlets and outlets must not be interchanged.All gases must be supplied to the unit already
processed. When using this unit with corrosive sample gases, ensure that these gases do not contain components harmful to the gas lines.
Admissable gas pressure for sample and test gases is 1500 hPa.
Exhaust lines must be laid inclined downwards, depressurized, protected from frost and according to applicable regulations.
If it is necessary to disconnect the gas lines, the unit’s gas connectors must be sealed with
PVC caps to avoid polluting the internal gas lines with condensate, dust, etc.
To ensure electromagnetic compatibility (EMC), only shielded cables (supplied by us on re-
quest, or of equivalent standard) may be used. The customer must ensure that the shielding is correctly tted. Shielding and terminal housing must be electrically connected; submin-D plugs and sockets must be screwed to the unit.
When using optional external adapters (submin-D to screw-type terminal), protection from electromagnetic interference can no longer be guaranteed (CE compliance pursuant to EMC guidelines). In this case the customer or operating company functions as a system builder
and must therefore ensure and declare compliance with EMC guidelines.

X-STREAM XE

1.2.1 Materials Used

Various materials are available to allow the analyzer to be customized to your needs. The materials used are selected based on
the characteristics of the sample gas, e.g. diffusion rate, corrosiveness, temperature and pressure. Among those available are Viton
®
,
PFA and stainless steel.

1.2.2 Safety Filter

The analyzers are generally tted with an internal stainless-steel lter. This lter is not
a replacement for any dust lter in the prepa-
ration of the gas, but represents a last line of
defence.

1.2.3 Gas Inlets and Outlets

Rackmounted and tabletop devices are tted
with PVDF inlets and outlets (ø 6/4 mm) as standard. Alternatively, Swagelok™ or stain-
less steel ttings (ø 6/4 mm or
1
4 in).
Wall-mounted eld housings are supplied with Swagelok™ or stainless steel ttings (ø
6/4 mm or 1⁄4 in).
Other materials available on request.
X-STREAM XEFD units are always supplied
with ame arrestors and stainless steel ttings
(ø 6/4 mm or
1
4 in).
Fieldhousings and 19 in analyzers provide up
to 8 gas ttings, so if featuring ve channels,
this requires at least two channels in serial
tubing.

1.2.5 Infallible Containments

Infallible containments are gas lines which,
due to their design, can be regarded as per-
manently technically tight. This is achieved
by, for example, welded joints, or metallically
sealing joints (e.g. tap connectors and bin-
ders), providing they are seldom disconnec-
ted. Gas lines congured in this manner can be used for measuring noxious, ammable
and explosive gases. At the time of going to
press, infallible containments are available
for thermal conductivity analysis (TC) only.
Further information about infallible contain-
ments can be found in the separate instruction
manual supplied with these units.
Infallible containments do not render it unnecessary to regu­larly test for leaks, e.g. following lengthy breaks in service, sub­stantial alterations, repairs and
modications.
Read the separate instruction manual giving detailed instruc­tions on the conguration, ope­ration and maintenance of units fitted with infallible contain­ments.

1.2.4 Tubing

Unless otherwise specied, the analyzers
are supplied with Viton
®
or PVDF piping
(ø 6/4 mm or 1⁄4 in). Other materials (e.g.
stainless steel) can be used, depending on
the application.

1.2.6 Optional Components for Gas Lines

Instruction Manual
HASXEE-IM-HS
10/2012
The analyzers can, as an option, be tted with
further components. Not all components are
available for all analyzer types:
internal sample gas pump
internal valve block
internal ow sensors
internal ow monitor switch
internal barometric pressure sensor
internal temperature sensors.
1.2.6.1 Internal Sample Gas Pump
An internal sample gas pump is used when
the sample gas is under insufcient pressure. It ensures a constant ow of sample gas (max.
2.5 l/min through the analyzer).
When in internal pump is tted, the relevant
parameter in the software setup dialog is set to Yes (
6-88). The pump can be con-
trolled either manually through a software
menu or optionally by a digital input.
Note!
Gas pressure is limited to atmospheric, if an internal pump is used!
1.2.6.2 Internal Valve Block
An internal valve block allows all necessary
gas lines (zero gas, span gas, sample gas) to remain permanently connected to the analyzer. Valves are then activated automa­tically when required (e.g. during automatic
calibration). When an internal valve block is tted, this
is shown in the relevant software setup dialog as either Internal or Int+Ext (
6-88). The valves are controlled by either
a software menu, optionally by digital in-
put, or automatically during autocalibration.
Depending on the model, up to two valve
bocks can be tted.
1.2.6.3 Internal Flow Sensor
Up to two internal ow sensors can measure the ow of gas and, compared to the ow monitor switch can provide a ow reading.
They also can activate an alarm signal in the event of a failure.
The alarm level for ow sensors is operator
adjustable to up to 2000 ml/min. Depending
on the model, up to two sensors can be tted
and evaluated separately. When a sensor is tted, the relevant parame-
ter in the software setup dialog is set to Yes (
6-90).
If the current ow rate is too low, a status
message is displayed and the parameter under CHECK REQUESTS.. is set to Yes
(
Chapter 8 'Troubleshooting').
1.2.6.4 Internal Flow Monitor Switch
An internal ow switch monitors the gas ow
and activates an alarm signal in case it is
not sufcient. Compared to the ow sensore it does not provide a ow reading, but only indicates if the ow is sufcient, or not.
The alarm level for the internal ow switch is xed and not operator adjustable. Additional external switches may be used and connected via digital inputs. All tted ow switches are
evaluated to share a common alarm. When an internal ow switch is tted, the re-
levant parameter in the software setup dialog is set to Yes (
If the current ow rate is too low, a status
6-88).

If such a sensor is installed in the unit, the related menu shows the entry Internal ( 6-88).
Depending on the conguration of the unit or
the demands of the application, temperature sensors can measure the unit’s internal tem­perature or selected measurement channel components.
If such sensors are installed in the unit, this is indicated in the installed options menu (
6-88).

1.2.6.7 Optional Heated Area
Instruction Manual
HASXEE-IM-HS
10/2012
The physical components can be optionally
separated from the electrical components
by means of a special box (not an option for ½ 19 in units). This can be done for one or both of the following purposes:
Firstly, the box allows the physical compo-
nents to be regulated to a temperature of
approx. 60 °C, avoiding condensation of
gases or minimizing the inuence of varying
environmental temperatures.
Secondly, the box can be purged with, for
example, inert gas (enclosure purge). The purge gas is rst fed through a separate t­ting, purges the electronic components, then
oods the box and leaves the instrument via another tting.
Purging in this manner can be useful when
measuring very low concentrations (e.g. of
CO or CO
): the expulsion of ambient air

avoids adulterant outside inuences. Alternatively, enclosure purging can be used
to secure enhanced protection for electronic parts and operators from corrosive or toxic gases: any leaking gas is expelled from the housing and does not escape into the vicinity of the unit or come into contact with any elec-
tronic components located outside the box. In either case, the purge gas outlet should be
connected to an exhaust gas line.

1.3 Interfaces
All analyzer types are tted with one analog
electrical output for each channel, four status relays, 2 Ethernet interfaces and a serial ser­vice interface as standard.
As an option, further interfaces can be added.

1.3.1 Analog Outputs

By default each X-STREAM analyzer is t­ted with one output per channel, which can transmit data on concentration levels to an
external data acquisition system. Up to ve analog outputs can be installed.
The analog outputs support several operation modes, such as 4-20 mA, 0-20 mA, as well
as the NAMUR NE 43 specications (incl. Live Zero). Operation modes can be set in a
software menu ( 6-62). The factory setting for analog outputs is
4-20 mA.
Depending on the unit conguration, all in-
terfaces are accessible via either SubminD
connectors or screw terminals
.
X-STREAM analyzers support up to five analog outputs, which, however, do not al-
ways need to be assigned to measurement
channels which are physically present: If
a unit features less than ve channels, the remaining analog outputs can be used to
transmit concentration levels with a different resolution; for example, a single-channel
analyzer could be set up as follows: Output 1: 0 … 100 % CO Output 2: 0 … 25 % CO
= 4 … 20 mA
2
= 4 … 20 mA

1.3.2 Status Relays

By default each analyzer provides four relays
outputs, precongured to signal the current
status of the unit according to the NAMUR
NE 44 specication ('Failure', “Maintenance request”, 'Out of specication' and 'Function
check'). However, the operator can assign different functions to the relays via software
menus. For a comprehensive list of available

same form of communication with a data acquisition system as does a serial interface.
Furthermore this interface enables to connect the analyzer to a network, providing web­browser access.
This interface is electrically isolated from the
unit’s electronic components and enables
the construction of a network of several ana­lyzers.
All supported Modbus parameters are listed

A serial interface with the Modbus protocol
allows communication with external data
acquisition systems. The interface enables
the exchange and modication of measure-
ment and analyzer signals, analyzer status monitoring as well as remote activation of procedures.
The serial interface is electrically isolated from the unit’s electronic components. RS 485 fa­cilitates the construction of a network of seve­ral analyzers. RS 232 interface only supports
communication between two end devices.

Measuring Principles
X-STREAM series analyzers support several measuring principles depending on the gas
component of interest. This provides best possible results, as the measurement can be chosen to optimally t the characteristics of the gas to be measured with respect to the
application. The following sections introduce
the available measuring principles highlighting their specic characteristics.

3.1 Infrared Measurement (IR) Ultraviolet Measurement (UV)

The non-dispersive measurement methods
described in this section utilize gas specic
light absorption in order to discriminate bet-
ween different gases. This is possible, as any
gas possesses distinct absorption characte-
ristics. The selective measurement of these
absorption lines can be used to identify gas components. The amount of light absorbed by the absorption lines is a direct measure
of the gas concentration. One can distinguish between two different ty-
pes of non-dispersive measurements differing how wavelength selectivity is accomplished.
It is essential for gas specic concentration
measurements, to selectively detect only light
of the absorption line wavelengths of the gas
of interest. T ypically a gas selective detector is used for NDIR measurements. For NDUV the
selectivity is achieved by an additional optical lter, as the detector itself is not wavelength
selective. In some applications, a pyrodetector is used for NDIR measurements. This type of detectors is not wavelength selective, hence
these setups also use an optical lter to narrow
their wavelength response function.
The assembly of a NDIR and NDUV channel is shown in Fig. 3-3. For NDIR a broad-band IR
light source is used to generate the light, while
NDUV measurements utilize a narrowband UV uorescence source, already adopted for the absorption lines of the gas of interest. Part of this adoption is done by a specially selected optical lter in the adaptor cell.
The diameter of the light beam emitted from the sources is adjusted to completely ll the
opening of the split analysis cell. After traver ­sing the analysis cell, the light passes through
a lter cell which adjusts the beam diameter to
the chopper opening and the diameter of the active detector area. The chopper wheel used is designed to allow an intrinsically referenced measurement. The details of this new patent
pending method are described in section 3.1.1.
Which measurement (UV / IR) to use for
a specic application depends on the gas component to be measured and the required
measurement performance.

3.1.1 IntrinzX Technology

The IntrinzX technology is an enhancement of the well established “proof peak” techno­logy with automatic sensitivity control, known from the MLT gas analyzer series. While the “proof peak” provided only one reference measurement per chopper wheel revolution, the IntrinzX technology provides four reference measurements per revolution. The patent pending IntrinzX technology has been intro­duced into the market with the launch of the X-STREAM X2 gas analyzers.
Using the new IntrinzX chopper wheel, the reference and the measurement signal are

modulated with 4 and 5 times the basic re­volution frequency, respectively. As a result, the proof peak process is integrated into the
measurement information, in contrast to being articially inserted in the measurement signal.
Frequency ltering separates the sum signal
into measurement and reference signal ( Fig. 3-1). This results in a permanently referenced
signal by dividing the integrated reference level by the integrated measurement level for
each revolution. Therefore the IntrinzX technology provides
many outstanding features:
High dynamic measurement ranges (e.g.
0-200 to 50,000 ppm CO), which cannot be obtained with standard photometric
technologies
Reduced temperature dependency
High sensitivity for lowest measuring ranges
This leads to cost saving effects for the cu­stomer:
One bench enables measurements of low & high ranges
Low & high concentration in raw and clean
gases
Small and large ranges before and after scrubbers
Measurement of carbon bed breakthrough / catalyst efciency
Mobile measurements at different sampling
points / locations
Easy adaption to different applications
(universities, laboratories)
Supports automotive engine testing
Benches to be used in TOC applications for measurements of low and high carbon
content
Fewer number of benches & cells
Easier eld repair and replacement of parts
Easy adjustment of low measuring ranges
in the eld
Reduced maintenance
Extended span calibration intervals
Minimized demand for test gases Due to the inherent correlation between refe-
rence and measurement side, span calibration can often be achieved by zero calibration.
The above listed IntrinzX features offer a
high degree of exibility with regards to ap-
plications:

3.1.2 NDIR Detector

The standard detector used for NDIR measure­ments is an opto pneumatic detector. It con-
sists of two chambers, lled with gas and
connected via a small channel (Fig. 3-2).
The gas lling is chosen to provide maximum overlap with the gas to be measured. Usually the gas to be measured itself is used.
A micro ow sensor, placed in the connecting channel, measures the ow between both chambers. As light is absorbed by the gas in the absorption chamber the gas temperature
changes resulting in an increase of volume of
the heated gas. The gas expands and ows towards the compensation chamber. When the chopper closes, no light is absorbed and
thus temperature and volume of the gas in the
absorption chamber decrease. Gas ows back from the (now) hotter compensation chamber into the absorption chamber. The absolute ow, detected by the micro ow sensor, in both cases is therefore a measure for the light absorbed while the chopper is open. This
directly correlates to the amount of light not
absorbed in the analysis cell and therefore
to the concentration of the measurement gas inside the analysis cell.
Using the divided analysis cell and the IntrinzX
chopper wheel enables simultaneous detection
of measurement and reference signal.

3.2.1 Paramagnetic Measurement

This oxygen measurement principle is based
on the paramagnetic characteristic of oxygen molecules:
Two cavernous glass spheres lled with nitro-
gen are arranged in a dumb¬bell conguration. This dumbbell with a platinum wire is mounted
rotatable inside a strong inhomogeneous ma-
gnetic eld. A small mirror is xed on the front side of the dumbbell, which reects light from a
light source towards two photo detectors (Fig.
3-4). The dumbbell is surrounded by another platinum wire, which is bent like a coil around
each glass sphere. It generates a magnetic
eld when supplied by an electric current to control the dumpbell´s deection.
Oxygen molecules within the sample gas are attracted be the magnetic eld due to
their paramagnetic characteristic and will
be concentrated into the area of the highest eld strength in the inhomogeneous eld. In doing so they displace the nitrogen lled
glass spheres. This generates a torque on
the dumbbell which depends on the oxygen concentration in the sample gas. The dumbbell starts to rotate and the light reected by the mirror on the dumbbell generates a signal on one of the two photo detectors. Initiated by the photo detector signal a preamplier drives a
current through the platinum wire surrounding
the dumbbell. This generates a compensating
magnetic eld and rotates the dumbbell back
into its zero position. The compensating cur­rent gives a direct and linear measure for the oxygen concentration within the sample gas.
The paramagnetic oxygen detector also
con¬tains a temperature sensor for compen-
sation and a heating ele¬ment to keep the
detector at approx. 55 °C.
Several variations are available including
corrosion resistant, solvent resistant and/or
intrinsically safe (for measuring ammable
gases) versions.

The electrochemical oxygen (eO

2
key components are a lead anode (1) and a
gold cathode (2) surrounded by a special acid
electrolyte (3). The gold electrode is integrated solid with the
membrane,which is a non-porous uororesin membrane. Oxygen which barely diffuses through the membrane is electrochemically
reduced on the gold electrode. The temperature compensating thermistor and
adjusting resistance are connected between
the cathode and anode. The current genera-
ted by oxygen reduction is converted into a voltage by these resistances.
The value of the current owing to the thermi-
stor and resistance varies in proportion to the oxygen concentration of the measuring gases
which contact the membrane. Therefore, the
voltage at the terminal of the resistances is used for the sensor output to measure the oxygen concentration.

In consequence of its design the sensor‘s lifetime is limited and depends on theoretical designed life and oxygen concentration. The

for end of lifetime: The sensor is weared when
the output in atmosphere is below 70 % of the initial output. The period till this can be calculated by

The sensor‘s designed lifetime under constant

to approx. 42,857 hrs, corresponding to
approx. 5 years.
An indicator for end of lifetime is a reduced
output signal. In this case the sensor must be
replaced to ensure accurate measurements ( Chapter 7 "Maintenance").
Note!
The given values are for reference only! The expected lifetime is greatly affected by the
temperature of the environment in which the

3.2 Oxygen Measurement
Due to the measuring principle the electro­chemical oxygen cell requires a minimum internal consumption of oxygen (residual humidity avoids drying of the cell). Supplying cells continuously with dry sample gas of low grade oxygen concentration or with sample
gas free of oxygen could result in a reversible detuning of O
sensitivity . The output signal will
2
become unstable, but response time remains
constant. For correct measurement the cell needs con-
tinuously to be supplied with concentrations of at least 0.1 Vol.-% O
. We recommend to
2
use the cells if need be in alternating mode,
means to purge cells with conditioned (not
dried, but dust removed) ambient air when
measurement pauses. If it is necessary to interrupt the oxygen sup-
ply for several hours or days, the cell has to
regenerate (supply cell for about one day with ambient air). Temporarily ushing with nitrogen
(N2) for less than 1 h (e.g. for analyzer zero-
ing purpose) has no inuence on measuring
characteristics.

3.2.3 Electrochemical Trace Oxygen Measurement

X-STREAM XE
For trace oxygen measurements (tO
electrochemical sensor technology is used, see Fig. 3-9. The sensor is a self contained disposable unit which requires no mainte­nance. The sensor utilizes the principle of electrochemical reaction to generate a signal proportional to the oxygen concentration in the sample.

Fig. 3-9: Trace Oxygen Sensor Design Principle

The sensor consists of a cathode and anode
which are in contact via a suitable electrolyte. The sensor has a gas permeable membrane
which covers the cathode allowing gas to pass into the sensor while preventing liquid electrolyte from leaking out.
As the sample diffuses into the sensor, any oxygen present will dissolve in the electro­lyte solution and migrate to the surface of the cathode. The oxygen is reduced at the cathode. Simultaneously, an oxidation reac­tion is occurring at the anode generating four
electrons. These electrons ow to the cathode
to reduce the oxygen. The representative half cell reactions are:
anode: cathode: in total:

This ow of electrons constitutes an electric
current which is directly proportional to the concentration of oxygen present in the sam-
ple. In the absence of oxygen, no oxidation/
reduction reaction occurs and therefore no current is generated. This allows the sensor
to have an absolute zero.
3.2.3.1 Special Hints This sensor is a consumable
and requires replacement pe­riodically. (To determine if the sensor requires replacement, see the troubleshooting section of this manual)
Remaining lifetime counts down when the sensor is in contact with oxygen.
For above reasons, the analyzer is shipped with the sensor as extra item in a sealed bag!
The sensor must be installed before analyzer startup, accor­ding the instructions shipped with the sensor!
Always consult the separate instructions, shipped with the sensor , before intending to start calibrations! Violation may re­sult in a damaged sensor!

After replacement purge gas paths with inert gas (nitrogen (N
) or sample gas as soon as
2
possible to avoid prolonged exposure of the
sensor to high concentrations of oxygen. The longer the sensor is exposed to air , the longer it will take for the sensor to recover to low ppm levels. When installing a new sensor or
starting the instrument for the rst time, it may
take as long as eight hours for the analyzer to purge down to the lowest operating range.
After initial startup or startup following a pro­longed shutdown, the analyzer may require extended time to recover to the range of
measurement. Commonly, this is caused by the introduction of ambient air into the sample
and/or vent lines to the sensor. The presence
of higher than normal levels of oxygen at the sensor will cause the sensor electrolyte to be­come saturated with dissolved oxygen. When the instrument is placed in operation, the sen­sor must now consume all excess dissolved
oxygen above the desired measuring level. All analyzers with electrochemical tO

to disconnecting the gas lines! Then the gas line ttings have to be closed for transport or

The bridge output signal (U
) is adjusted to
Br
zero when in rest position (no gas ow). By
default the reference gas path is closed (not
own through by gas). When sample gas is
supplied, the sensors in the sample gas path are cooled due to the thermal conductivity ef-
fect: The gas absorbs heat and carries it away
from the sensors. This tunes the Wheatstone
bridge and generates a signal proportional to
the thermal conductivity. Additional electronics linearizes and conditi-
ons this signal to provide usefull measuring
values.Depending on application, it is possible
to supply a reference gas to the bridge‘s re-
ference side. The output signal in this case is proportional to the difference of the thermal conductivities of sample and reference gas.

Some denitions:
The dew point
is the temperature in Deg C
to which a given parcel of humid air must be cooled, at constant barometric pressure, for
water vapor to condense into water. The con­densed water is called dew. The dew point is the saturation temperature.
Humidity is the amount of water vapor in the
air. Relative humidity is dened as the ratio
of the partial pressure of water vapor (in a gaseous mixture of air and water vapor) to the saturated vapor pressure of water at a given temperature.
The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100 % in­dicates the dew point is equal to the current temperature and the air is maximally saturated with water. If the dew point remains constant and temperature increases, relative humidity will decrease.

How does dew point measurement connect with trace moisture measurement?

3.4.1 Special Operating Conditions

The sensor is completely calibrated with all calibration data stored in its ash memory and does not require recalibration:
If the sensor is included into a calibration
procedure, it might end up with a wrong
calibration and unusable sensor. Therefore
the analyzer's trace moisture measurement
channel is congured to be excluded from
autocalibration procedures, by default cali-
brating all channels. This exclusion is done by factory setup and cannot be changed.
For proper measurement results we re­commend to exchange the sensor regularly after 12 months of operation.

H2S sensors are electrochemical cells that operate in the amperometric mode. That is, they generate a current that is linearly propor­tional to the content of H2S in the sample gas.

The working electrode (also called the sensing electrode) is designed to optimize the oxidation
of Hydrogen Sulde. This electrode allows the gas to come in contact with both electro
catalyst and electrolyte to create a threephase interface of gas, liquid and solid.
The other two electrodes in the cell, the counter electrode and the reference electrode usually have a similar chemical composition to the working electrode.
All three electrodes are stacked parallel to each other, as illustrated in Fig. 3-15. Three metal strips connect each electrode to the
three pins outside of the sensor body.
The cell electrolyte provides ionic electrical
contact between the electrodes, usually with the aid of hydrophilic separators (labelled “wetting lters” in Fig. 3-15) to allow capillary

transport of the electrolyte which is usually
sulfuric acid between 3 and 7 molarity.
A potentiostatic circuit maintains the potential
of the working electrode at a xed value with
respect to the reference electrode potential. The working electrode is the surface where
the electrochemical oxidation of H2S occurs. A high surface area catalyst is used to optimize the sensor performance, resulting in a high sensor capacitance: typically 50 mF to 200 mF .
The counter electrode balances the reaction of the working electrode – if the working electrode
oxidises the gas, then the counter electrode must reduce some other molecule to generate an equivalent current, in the opposite sense.
The reference electrode anchors the working electrode potential to ensure that it is always working in the correct region of the current­voltage curve. It is important that the reference
electrode has a stable potential, keeping the
working electrode at the right electrochemical potential to maintain a constant sensitivity, good linearity and minimum sensitivity to interfering gases.
The potentiostatic circuit ensures that the counter electrode is provided with as much current as it needs, also maintaining the wor-
king electrode at a xed potential, irrespective
of how hard it is working.

Moisture and oxygen are needed in the sample gas for the electrochemical reactions to take
place. If concentrations of above components
are too low , the sensor's sensitivity decreases.
Therefore a purge cycle with ambient air can be implemented by programming the internal
PLC.
If this option has not been ordered, the cu-
stomer is responsible to take care of regularly
purging the sensor. See the separate docu­mentation provided together with every sensor for information on how to properly setup such a procedure.

3.6 Measurement Specications
Note 1!
Not all data listed are applicable to all analyzer versions (e.g. 60 °C thermostatically controlled box is not available for electrochemical and trace oxygen, nor for
1
219 in instruments).
Note 2!
For NDIR/UV/VIS measurements, take into account that
sample gas may diffuse or be released by leakages into the analyzer enclosure
if existent in the analyzer surroundings, the component to be measured may enter the enclosure.
Concentrations then may increase inside the enclosure. High concentrations of the component
to be measured inside the enclosure may inuence the measurement by unintended absorption, which could cause drift of the measurement.
A remedy for this issue is to purge the housing with gas not containing the component of interest.
All performance data are veried during the manufacturing process for each unit by the following
tests:
Linearization and sensitivity test
Long term drift stability test
Climate chamber test
Cross interference test (if applicable)
