The sodium measurement as used in this instrument is based on a
proven glass ion sensitive electrode. The logarithmic response can

The detection limit of the system. This term
[mV]

[ppb]
[ppb]
is used to define the curvature of the electrode response near the detection limit. It
depends on pH, other interferences like
potassium and other ions, and temperature.
C
ISO
The Sodium concentration in the sample
[ppb]
where the measured potential of the electrode pair is temperature-independent. It
equals the reference point for the temperature compensation.
Sodium measurements below 1 ppb require a special glass formulation for the sensing electrode response.
Ammonium and pH interferences from the unconditioned sample
are eliminated by a suitable reagent.
The measuring limit of 0.001 ppb sodium requires the conditioning
of the sample to a minimum of pH 12 while sample integrity has to
be maintained. The best results are obtained with Disopropylamine
(DIPA).

On-line
operation
Control of re-
agent addition
During on-line operation the AMI Soditrace works in the Mode
<Low Level>.
The sample enters the system at the sample inlet [P] and flows into
the constant head [J].
Adjust the flow regulating valve [N] so that always a small part of
the sample flows through the overflow tube [O] into the waste. This
adjustment ensures a sufficient sample flow through valve V2 and
V3 and then via airlift pump [L] into the measuring chamber [H]
where the Sodium electrode [C] is installed. This arrangement
guarantees a very constant sample stream of 20 ml per minute and
at the same time a sample conditioning to pH 12 (see Control of
Reagent Addition below).
To prevent any back-diffusion and thus contamination in the measuring chamber [H], the sample overflows into the calibration chamber [I] from there into the reference chamber [G] and through the
low level overflow [G
ture is measured in the reference chamber with the temperature
sensor [A]. It is used to compensate the Sodium reading following
the Nernst algorithm.
The reagent addition system is driven by the air pump [F]. The Air
flows through the energized valve V4 to the reagent bottle [Q],
where it is picking up reagent vapor. From there it flows to the air lift
pump where the sample is enriched with DIPA.
If valve V4 is not energized, the air flows direct to the airlift pump [L]
via valve V4 and V5.
The conductivity sensor [K] measures the amount of reagent added
to the sample, and a PID controller activates or deactivates valve 4
so that the conductivity reading remains constant. A conductivity of
450 µS/cm should be maintained for low Sodium readings. Upon
exhaustion of the reagent, the conductivity will fall below the setpoint and trigger an error message.

Regeneration The system automatically regenerates the sodium electrode [C] ac-
cording to the programmed interval or 12 h before a calibration. By
opening valve V5 the regeneration solution [E] flows through the
airlift pump [L] and etches the sodium electrode [C].

Calibration Before the 3-point calibration starts, valve V1 closes and the mea-
suring cell is filled until the sample overflows via the overflow high
level [GH] into the waste. Then the sample flow is stopped by deenergizing valve V2, and the trapped volume of sample circulates
in a closed loop through valve 2 and valve 3 driven by the airlift
pump (L).This circulation is called Mix, see figure below.

For the second calibration point, the calibration loop is filled and
flushed, twice. Again the sample is recirculated until a constant mV
reading is attained.
For the third calibration point, the calibration loop is filled and
flushed, seven times.
With three addition steps, an increase of one order of magnitude in
Sodium concentration is achieved.
Example Standard concentration: 5 ppm
Point No No of additions Final concentration [ppb]
1 110
2 230
3 7 100
The ability to produce 1 ppb Sodium concentration additions with
the factory calibrated injection loop, gives credibility to subsequent
measured values below 1 ppb.

The implemented calendar is based on the CRON format. It starts
with Sunday and ends with Saturday. Usually a month has three full
weeks and two weeks which are part thereof.
Therefore, if you program a task which has to be carried out weekly,
always program the task in the 2nd, 3rd or 4th week of a month.
Example:
In the table below it can be seen, that if a task is programmed on
Monday in the 1st week, it is not carried out because the week
starts only on Wednesday

6.9. Calibration
The 3-point calibration is used to recalculate the slope and determine the offset of the sodium sensor periodically.
The calibration consists of three steps. On each step an exactly defined amount of a known concentration of a standard solution is
added to the closed sample loop. After each addition the concentration is measured and at the end of the calibration slope and offset will be calculated and stored from these measuring values. For
a detailed description of the calibration please refer to

5.1.1 Ref. Electrode: Only Calomel is possible for this application.
5.1.2 Maintenance Plan: The menu Maintenance Plan includes all settings, necessary to carry out regularly maintenance tasks.
5.1.2.1 Start time. Enter the Time at which you want to start a task.
5.1.2.2 Calendar: The implemented calendar is based on the CRON format. It starts with Sunday and ends with Saturday. Usually a month
has three full weeks and two weeks which are part thereof.
Therefore, if you program a task which has to be carried out weekly,
always program the task in the 2nd, 3rd or 4th week of a month.
Example:
Looking at the table below you can see, that if a task is pro-
grammed on Monday in the 1st week, it is not carried out because
the week only starts on Wednesday!
