Measuring
principle
The sodium measurement as used in this instrument is based on a
proven glass ion sensitive electrode. The logarithmic response can
be described as follows:
E = EO + SINa * log {(CNa + CB) / CISO}
With the abbreviations
Sodium measurements below 1 ppb require a special glass formu-
lation 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).
EThe measured potential of the electrode pair. [mV]
EOThe measured potential when the Sodium
concentration in the sample equals Ciso.
[mV]
SINA The temperature dependent slope of the
electrode response (R*T / n*F).
[mV/
dec]
CNa The Sodium concentration in the sample. [ppb]
CBThe detection limit of the system. This term
is used to define the curvature of the elec-
trode response near the detection limit. It
depends on pH, other interferences like
potassium and other ions, and temperature.
[ppb]
CISO The Sodium concentration in the sample
where the measured potential of the elec-
trode pair is temperature-independent. It
equals the reference point for the tempera-
ture compensation.

AMI Soditrace
Product Description
On-line
operation
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 mea-
suring chamber [H], the sample overflows into the calibration cham-
ber [I] from there into the reference chamber [G] and through the
low level overflow [GL] and valve V1 into the waste. The tempera-
ture is measured in the reference chamber with the temperature
sensor [A]. It is used to compensate the Sodium reading following
the Nernst algorithm.
Control of re-
agent addition
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 set-
point 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].

Product Description
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 de-
energizing 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.

Product Description
When the valves are deactivated, the content of the calibration loop
is flushed into the measuring cell. For the first calibration point, the
calibration loop is filled once with standard and then flushed into the
measuring cell. The sample is then recirculated until a constant mV
reading is attained.

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
The ability to produce 1 ppb Sodium concentration additions with
the factory calibrated injection loop, gives credibility to subsequent
measured values below 1 ppb.
