Components locations
The components inside the unit are accessed by simply unscrewing the screws at rear and lateral
sides of the unit and removing the upper cover.
Mechanical components
This includes the following equipment:
– the solenoid valves and filter assembly (1 and 2),
– the internal "Zero Air" filter (activated charcoal) (6),
– the carbon kicker filter (activated charcoal) (18),
– the temperature controlled compartment (17),
– the photo multiplier tube (15),
– the UV lamp (13).
After passing through the inlet dust filter (1), the sample to be analyzed is sent to a block of two 3-way
solenoid valves (2).
These solenoid valves are used to select:
– either in "MEASUREMENT" mode, the gas sampling to be analyzed,
– or in "ZERO" mode, the filtered ambient air through the activated charcoal filter (6),
– or in "SPAN" mode, a span gas originating from:
x the permeation oven (19) if there is one (optional),
The permeation oven consists of an aluminum chamber inside which the permeation tube is
placed. This chamber is regulated at a temperature of 50 °C and ventilated by an additional
constant flow rate pump (20).
x or an outside calibration device.
The sample to be analyzed is drawn through a carbon kicker (14) aromatic hydrocarbon elimination
device to the reaction chamber (16) in which the fluorescence takes place. Fluorescence is detected
by a photo multiplier tube (15).
The temperature of the optical block is regulated at 43 °C by the microprocessor associated with a
probe and a heating resistance.
Outside the compartment, the "zinc ray" type lamp (13) generating the UV radiation is powered by a
stabilized voltage supply (11). The UV beam emitted is interrupted during the beginning of "ZERO
REF" by a shutter (12) in order to measure the PM tube black current.
The analyzed sample passes through a flow regulating restrictor and through the external tube of the
carbon kicker to eliminate hydrocarbon molecules. It is then expelled by a membrane pump (3).
The supply bloc 24V DC (20) enables to supply the whole necessary voltages.
If the user wants to modify the original supply voltage (230 V AC to 155 V AC), 2
options are necessary :
x
switch the A switch to the cut-out power supply
x
modify value of general fuse :
– from 0,6 A passes to 1,2 A for a normal analyzer,
– from 1,6 A passes to 3,2 A if the CH2S option is available.

Electronic part
– The signal output by the photo multiplier tube is amplified and converted into a digital signal on the
Module board (7). This board also:
x supplies DC voltages at + 15 V, 15 V, + 5 V,
x detects any alarms, transmits these alarms to the microprocessor board and signals them on
the corresponding output connector,
x performs digital/analog conversion of measurement values output by the microprocessor board.
– The microprocessor (7), calculates and stores measurement values, and manages alarms and
automatic cycles.
– The keyboard interface board (10) controls the dialogue between the microprocessor board and the
keyboard and the display unit.

Environnement S.A
THEORETICAL BASIS (FIG. 2.1)
Energy diagram:
Many developments in quantum mechanics at the beginning of this century enabled theoretical
physicists to conceptualize the processes involved in energy exchanges between a gaseous molecule
such as sulfur dioxide and its environment.
The diagram shown makes it easier to obtain a global understanding of the various phenomena due to
absorption of a radiation by the molecule.
Two essential comments clarify this diagram:
Energy levels are quantified and distributed in accordance with a structure that is different for molecule
electronic, vibrational and rotational levels,
At the considered wavelengths, the "electronic" scale of energies only includes the energy levels of
molecule valency electrons.
Also, a transition from one electronic level to another by absorption of a photon is always
accompanied by lower level vibrational and rotational transitions.
The mathematical formulation of molecular physics associates a spatial and temporal function called a
wave function to each state of the molecule, fully characterizing this state. A transition then occurs by
a new spatial distribution of the wave function.
Absorption and emission:
In its fundamental state Ee0, the SO2 molecule can only absorb sufficient energy photons to access
the first excited state on the electronic scale Ee1.
The energy of a photon is given by Einstein's relation:
E
hv
h
c
O
where O is the radiation wavelength output from a low-pressure zinc vapor lamp, namely O = 213.9 nm,
and h and c represent Plank's constant and the speed of light in a vacuum respectively.
The transition is denoted in the following form:
SO2 + h v o SO2*
As we have already said, the molecule always reaches a vibrational and rotational sub-level of Ee1,
namely higher than this sub-level. It then very quickly dissipates its vibration and rotation energy to
remain on level Ee1 a little longer (a few nanoseconds).
JULY 2002
2–3
AF22 MODULE
Environnement S.A
Duplication prohibited
Starting from Ee1, it can reach any sub-level of its fundamental state along different paths:
by fluorescence:
Kf
SO2 * o SO2 hv'
Based on the above,
firstly v' =
c
O'
is less than v, therefore O' > O,
secondly, O' can be equal to one of several values around an average length, since the sub-level
reached can be arbitrary (statistical distribution as a function of the temperature).
The monitor "observes" photons emitted through a filter centered on 350 nm.
by extinction:
Kq
SO2 * M  o SO2 M
where M represents another gaseous molecule.
The molecule then dissipates its energy mechanically and does not fluoresce. This is referred to as
"quenching".
by dissociation:
SO2 * Kd
o SO O
The energy Ee1 is sufficient to break the SO O link.
Kf, Kd, Kq denote quantum yields associated with each form of deactivation. They are related to
the life of state Ee1, and express probabilities attached to each reaction type. They are determined
from the integral, taken over the entire volume, of the product of wave functions of excited and

PRINCIPLE OF MEASUREMENT
The radiation intensity absorbed by sulfur dioxide in an optical chamber of length L follows the BeerLambert law:
ia = i0 x (1 – e-Lc)
where lo denotes the intensity at the chamber inlet, D is the characteristic SO2 absorption coefficient
and c = [SO2], is the concentration of the gas to be analyzed.
Also, the probability that an excited molecule will fluoresce is given by:
Kf
Kf Kq Kd
The fluorescence intensity received by the PM is then expressed in the following form:
If
G la
Kf
Kf Kq Kd
where G is a constant that depends on the illuminated part of the chamber seen by the PM.
Therefore:
if
In our case, D L c << 1 and 1 e
Gio
DLc
Kf
x (1 e D Lc )
Kf Kq Kd
can be developed to the first order as follows:
1e
DLc
#+DLc
We then obtain:
If
G lo Kf D L
c
Kf Kq Kd
E .c
The radiation captured by the PM is thus directly proportional to the SO2 concentration. This result is
the basis for the measurement technique used with the AF22M monitor.

TAKING SAMPLES AND ANALYSIS
The sample is taken by a Teflon tube connected to the back of the monitor through a pump placed at
the end of the circuit. A Teflon filter provides dust protection.

The sample to be analyzed is firstly filtered by an elimination device of aromatic hydrocarbon
molecule.

Figure 2-3 – Filtration of hydrocarbon molecules
This device consists of two concentric tubes. The internal tube is made of a special polymer (silicone).
The sample to be analyzed with aromatic HC molecules comes in the internal tube. Aromatic HC
molecules are transferred by permeation to the external tube (silicone) with effect that the transfer is
done in the direction: more HC molecules in gas to few HC molecules in gas.
The pump creates a vacuum in the external tube, the partial pressure of aromatic compounds
decreases due to activated charcoal filtration and molecules are evacuated to the outside of the
internal tube.

Analysis
The sample to be analyzed, exempt from HC molecules, is directed to a reaction chamber in which it is
irradiated by an ultraviolet radiation centered at 214 nm, the absorption wavelength of SO2 molecules.
A photodiode measures the ultraviolet radiation generated by the UV lamp, through a mirror. This
measurement is used during signal processing in order to compensate for any variation of the UV
energy.
Molecules restore a specific fluorescence in the ultraviolet, which is optically filtered between 300 and
400 nm at the outlet in order to eliminate some interfering gases. This fluorescence is visualized by the
PM tube placed near the reaction chamber.
At the start of each "zero-ref", a shutter is placed between the UV lamp and the reaction chamber inlet
for 40 seconds. This electrical zero corresponds to the PM tube darkness current and the offset
voltage of the preamplifier, incorporated into the signal processing, it eliminates the possibility of drifts
with temperature and time.
The PM tube signal is amplified and is converted into digital values for processing by a microprocessor
that calculates the average of measurement values, checks the alarms and carries out monitor
operation diagnosis. These various values and information are displayed on an alphanumeric display
unit on the monitor front panel.

AUTOMATIC RESPONSE TIME
In order to optimize its metrology, the AF22M monitor is equipped with a software function called
"automatic response time" which enables filtration of measurements depending on evolution of
concentrations of sulfur dioxide.
2.5.1
SIMPLIFIED PRINCIPLE OF OPERATION
An average of instantaneous readings is carried out corresponding to a minimum response time.
>MEAS@ AVERAGE
80
ª
º
«
¦1 >Pm signal @ »
» Reference zero
= « 16
«
»
« ¦ >UV detector signal @ »
¬ 1
¼
Then, a weighted average between the filtered values ( >MEAS@ FILTERED ) and the average
measurements ( >MEAS@ AVERAGE ) is recursively calculated according to the formula:
>MEAS@ DISPLAYED
>MEAS@ FILTERED (NEW)
X > MEAS@ FILTERED (OLD) Y [MEAS] AVERAGE
X +Y = 1
When the difference ( >MEAS@
FILTERED (OLD)
>MEAS@
AVERAGE
) exceeds a determined threshold, the
value of Y is increased, up to a maximum value of 0.98 which corresponds to a fixed response time of
TRMIN.
When >MEAS@
2.5.2
FILTERED (OLD)
>MEAS@
AVERAGE
is below the threshold, Y is progressively decreased.
PROGRAMMING THE RESPONSE TIME
The function of automatic response time may be activated or deactivated in the configuration Ö
measurement mode menu.
The minimum response time may also be modified in that menu.
See chapter 3 section 3.3.4.2 to obtain more information about programming of those functions.

CALIBRATION
3.4.1
OVERVIEW OF CALIBRATION AND CONCEPTS
Environnement S.A
To ensure the accuracy of the measurements performed using the AF22M monitor, the unit must be
regularly checked, calibrated and adjusted, following the quality assurance plan of the user.
– Check of zero and span point:
This operation consists of comparing the monitor response, for zero air and a span point of the
range used, to the gas standards used.
This check is used to measure the monitor drift in time without modifying the adjustment coefficient.
This check can be performed using the internal zero air and span.
Frequency: generally 24 hours in automatic cycle mode.
– 2-point calibration:
This is a procedure for checking and correcting the response of the monitor at zero and at a span
point located at approximately 80 % of the full scale of the measurement range used.
Frequency: monthly, or more frequently if the monitor requires it.
– Span (multi-point calibration):
This involves a complete check up of the monitor performance characteristics (linearity).
Frequency: quarterly, or following out-of-tolerance calibration check results requiring an
intervention on the monitor.
Note about gas generation devices:
For devices providing pressurized gas, it is necessary to provide an excess system to deliver the gas at
atmospheric pressure to the monitor inlet. The materials making up this device should be neutral for the gas
used. When used in an automatic cycle with a cylinder, provide a shut-off solenoid valve that can be remotecontrolled by the monitor (see figure 3.6).
Note about gas cylinders connections:
When the analyzer is equipped with the internal zero filter and/or the internal permeation bench, these
respective inlets are no more available (see figure 2-2), therefore during the calibration procedures the
calibration gas cylinders will be connected to the sample inlet

Zero air generation
– Check: internal zero filter.
– Calibration: cylinder of reconstituted air or zero air generator. The zero air should be free of any
constituent likely to be measured by the monitor and should not contain more than 0.0005 ppm of
SO2.
3.4.1.2
Span gas generation (SO2)
SO2 calibration gas source standards used for adjustments should be traceable to a National Institute
of Standard & Technology (NIST), Standard reference Material (SRM) or Certified Reference Material
(CRM) in accordance with EPA's Protocol n° 2.
If a permeation device calibration system is used, be sure to allow 24 hours for warm-up.
Zero air used for the dilution of standard gas concentration and for zeroing the analyzer should be the
same and contain less than 0.0005 ppm of SO2.
All fittings, valves, pneumatic lines and other components that may contact span test gas must be
fabricated with highly cleaned inert to SO2 material (i.e. stainless steel).
– Calibration check:
xCylinder of SO2 (1 % accuracy) with a concentration of approximately 80 % of the upper range
limit. The cylinder used should be regularly certified in accordance with the user's quality assurance
plan.
xOptional built in permeation oven with an SO2 wafer device. The concentration generated by the

be fabricated or coated with cleaned PTFE, glass or stainless steel.
Internal solenoid valves
During multipoint calibration the gas sources will be connected to the sample inlet of the monitor. After
this calibration operation, the gas sources will be connected to their respective inlets and a check will
be made to see that the monitor's response is identical on any inlet used. The various gas inlets can
therefore be used for zero and span point checks and for 2-point calibration of the monitor. Otherwise,
the solenoid valves must be cleaned or replaced.
3.4.2
CHECK OF ZERO AND SPAN POINT
3.4.2.1
Facilities required
– "Zero" air:
a sufficient quality of "zero" air is obtained using the monitor "ZERO AIR" filter (Purafil/activated
vegetable charcoal).
– Span point:
x SO2 gas cylinder, which concentration is below 1 PPM and connected to the monitor "span gas"
inlet.
x Or internal permeation oven with SO2 tube (connected to monitor "span gas" inlet). The
concentration generated by the oven is recorded on the check sheet.
x Or portable calibrator (type VE3M) equipped with an SO2 tube and connected to the monitor
"span gas" inlet.
NOTE : If the analyzer is equipped with an internal permeation oven, the sampling input must be used
to connect the reference cylinder or the portable calibrator.
3.4.2.2
Procedure
– Zero check:
Select the monitor "zero air" inlet using the
Zero
key or appropriate inlet if required and wait for the
measurement to stabilize. The reading should be less than + 2 ppb. If this is not the case, a zero
adjustment is necessary.
– Check of scale point:
Select the gas inlet where the span gas is connected using the
Span
key or the
Sample
key, as per the
above note, and wait for the measurement to stabilize. The result will be compared to the
concentration generated by the device used, taking into account its accuracy.
If the difference between span gas and reading is more than + 10 %, a span adjustment is
necessary.

Overview
Duplication prohibited
The minimum device will be made up of a diluter, a certified cylinder of SO2 (1 % accuracy), the
calibration of which can be traced to reference materials from the National Institute of Standards
(NIST) for calibration in the framework of measurements according to the US EPA, and a zero air
generator. Figure 3.7 shows an example of a typical calibrator.
The gases will be applied to the sample inlet of the monitor at atmospheric pressure.
Calibration of the monitor requires generation, in addition to the zero, of 6 gas concentrations (for
example, 15 %, 30 %, 45 %, 60 %, 75 % and 90 % of full scale of range used). The dilution air must
be the same as the zero air.
It is advisable to connect the analog output of the monitor to a strip chart recorder for acquisition and
processing of the data.
3.4.4.2
Equipment Required
– Diluter:
x flow regulators: they must regulate flow rates to the nearest r 1 %.
x flow meters: they must read and record flow rates to the nearest r 2 %.
x mixing chamber: its shape and volume should allow a homogeneous mixture of SO2 and
dilution air.
– Manifold:
The manifold must include at least one outlet for the monitor and one outlet for the excess flow
meter. The outlet must have a sufficient diameter so as not to create any load losses at the inlet of
the monitor. The outlet of the excess flow (at least 20 % of the total flow rate) will be designed so
that the pressure in the manifold is quite near the atmospheric pressure (no overpressure), but so
that the ambient air cannot be back scattered.
– Dilution air (zero air):
Zero air generator or cylinder of reconstituted air free of any contaminants likely to be measured by
monitor and of which the SO2 concentration does not exceed 0.0005 ppm.
– Span gas (SO2):
Certified cylinder of SO2 in air at 1 % of which the concentration will allow generation of 6 ranges
between 15 % and 90 % of the full scale of the measurement range used.

INTERNAL PERMEATION OVEN (OPTIONAL)
The scale point check can be performed using a permeation oven equipped with a SO2 source.
– Principle:
The SO2 used is maintained in a state of liquid/vapor phase equilibrium in a closed cylindrical tube
fitted with a polymer diaphragm. Due to the differential partial pressure of the gas on either side of
the diaphragm and the diaphragm "permeability", gas is diffused toward the outside of the tube.
The weight of the gas diffused by unit of time, called "permeation rate", depends on several
parameters: type of gas, thickness, surface and nature of diaphragm, partial gas pressures on
either side of diaphragm, temperature.
– Setup:
The permeation tube is placed in a block which is thermostat-controlled to 50 °C (± 0,1 °C) and
continuously ventilated with a scavenging gas whose flow is regulated to about 45 l/h. The rinsing
gas is filtered by an active charcoal filter located at the rear of the analyzer and directly connected
to the inlet of the permeation oven. The outlet of the permeation oven (PTFE plug) is connected to
the "span gas" inlet of the analyzer.
When this inlet is selected, the monitor samples a part of the generated gas and thus measures the
concentration of this gas.
– Procedure:
x The internal oven is selected using the "span" key, or automatically on a calibration cycle. Once
stabilized, the SO2 measured by the monitor must be compared to the concentration recorded
on the check sheet.
x Since SO2 permeation is very sensitive to the quality of the rinsing air, the condition of the
activated vegetable charcoal filter should be checked periodically.
x The oven temperature is set using the Tests Ö Mux signals function on channel No. 14 (see
Table 3.3).
x The system operating temperature range is 10 to 35 °C (ambient temperature).
x When setting into service or following an extended shutdown period, the stabilization time is
about 24 hours.
x The permeation source supplied with the monitor has an autonomy of about 16 months.
If the monitor is not used, the source should be removed from the oven, and placed in its
original package with the desiccant and absorbent bags, then stored in a cool, ventilated
location.

– To maintain the best precision, the following characteristics should be checked regularly:
x flow rate of oven diluent air,
x permeation tube rate (theoretically constant).
A differential weighing using an accurate balance should be performed to the 10 th, or better to the
100 th of mg.
Calculation of permeation (P) and (CG) concentration rates generated by oven:
m0 = Initial weight of tube (ng)
m1 = Final weight of tube (ng)
m0 m1 = Weight of SO2 diffused (ng)
t = Time between two weighings (min)
P = (m0 m1) / t = Tube permeation rate (ng/min.)
F = Real total air flow rate passing through the oven (CC/min.)
Km = Molar coefficient, for SO2 = 0.382
CG = Km x P / F = Concentration of span gas generated (ppm)
NOTE :
These calculations must be repeated each time a permeation tube is changed, or, more simply, the
concentration generated by the new tube can be determined by reading the concentration on the oven
just after calibration of the analyzer (see section on calibration).

4 Remote controls.
The ESTEL board enables dialog with the measurement module and relieves it of the Inputs/Outputs
functions. It enables remote control and/or remote signalling of certain functions as: "measurement",
"zero", "calibration", "alarm".
The analog inputs are used to connect independent monitors in order to follow-up, for example,
weather parameters.
The analog outputs enable to send numeric parameters (gas concentration to be analyzed, MUX
channels) to analog independent peripherals in order, for example, to store and process several data
of several months.
Equipped with an ESTEL board, the analyzer can work as an autonomous unit of analysis.

The user (customer) carries out himself the operation at input of his acquisition system.
Operating mode:
Connect each analog output, previously configured into 0-10 volts, to ground through 2 resistances
of equal value within 500 and 1000 ohms.
Take off the divided-by-2 signal at terminals of the resistance that is connected to the ground.

« Analog output » Function
This screen enables to assign the parameters to the analog outputs for the ESTEL board whose n°
indicated in the field « No » is highlighted. These parameters are:
x
Concentration of the analyzed gases,
x
Auxiliary channels (multiplexer),
x
Analog inlets.
REMINDER : On an ESTEL board, analog outputs can be configured into: 0–1 Volt, 0–10 Volt, 0-20
mA, 4–20 mA.
Four ranges are available and correspond to the full scale of the analog output, units are those of the
parameters displayed in the « Signal » column.
When signal value is higher than the full scale of the current range, the analyzer switches to the next
higher range. It switches again to the lower range when measurement again passes under 85%.

The Ax+B calibration curve is used to adjust the mV signal of the taken-into-account analog output.
The « Test » column is used to test the 5 analog outputs and to adjust the points number.
For a range 1 :
– 0 point (lower scale of output) @ 0 volt obtained at output,
– 4000 points (higher scale of output) @ 1 volt obtained at output.

Programmation
The hereafter screens (§ 1.3.1 à § 1.3.3) are given as example.
Refer to technical manual of the analyzer in which SOREL board is installed.
The analyzer automatically detects the presence of one or several SOREL and/or ESTEL boards and
offers menus enabling the user to adjust and configure each board.
x
In CONFIGURATION menu of main software program, the "Analog outputs", "Analog
inputs", "Relays and remote controls" items are only displayed if the SOREL and/or ESTEL
board option is available. Only, the sub-menu "Relay and remote controls is necessary
to program the SOREL board.
x
In the TESTS menu of the main program, the item "ESTEL card" is displayed if one
SOREL board at least is detected.
The same screen as for ESTEL board must be used, but it is necessary not to take into
account of data about analog inputs and outputs.
