2. Product Description
Application Sodium measurement is used for quality control in high purity water
applications and to monitor break through of mixed bed ion exchang-
ers, condenser leaks and the prevention of caustic corrosion of tur-
bines. The AMI Sodium P is suitable for samples with a pH value
higher than pH7. For samples with a pH lower than pH7, use the AMI
Sodium A.
Measuring
principle
The sodium measurement used in this instrument is based on a
potentiometric measuring method. For this purpose a proven sodium
ion sensitive glass electrode and a reference electrode is used.
These two electrodes produce a different electrical potential which is
used to calculate the sodium concentration of the sample. According
to Nernsts Law, the ion concentration depends on the temperature,
therefore a temperature sensor measures the sample temperature.
With the current temperature the measuring value is expressed for
the standard temperature of 25 °C by using programmed tempera-
ture compensation curves.
Sodium measurements below 1 ppb require a special glass formula-
tion for the sensing electrode response. Ammonium and pH interfer-
ences from the unconditioned sample are eliminated by a suitable
reagent. The measuring limit of 0.1 ppb sodium requires the condi-
tioning of the sample to a minimum of pH 10.5 while sample integrity
has to be maintained. The best results are obtained with Diisopropyl-
amine (DIPA).
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear or bilinear) or as continuous control output (control pa-
rameters programmable).
Current loop: 0/4 - 20 mA
Maximal burden: 510 Ω
Third signal output available as an option. The third signal output can
be operated as a current source or as a current sink (selectable via
switch).
Relay Two potential-free contacts programmable as limit switches for mea-
suring values, controllers or timer for system cleaning with automatic
hold function.
Maximum load: 1 A / 250 VAC

On-line
Operation
The sample flows into the constant head [A] via the sample inlet [D]
and the flow regulating valve [C]. Adjust the flow regulating valve so
that always a small part of the sample flows through the overflow
tube [M] into the waste. This adjustment ensures a sufficient sample
flow through the flow cell [K].
First, the sample flows into the measuring chamber [K1] where the
sodium electrode [G] is installed and the sodium concentration of the
sample is measured. From there it flows into the measuring chamber
[K2] where the pH electrode [F], the temperature sensor [H] and the
reference electrode [E] are installed and thereafter it flows via flow
cell [K3] through the sample outlet [L].
During on-line operation, the standard bottle holder [R] is completely
turned down, and the sample flows from the constant head [A] into
the reaction tube [B]. Due to the different level of the constant head
and the flow cell, a negative pressure is created in the reaction tube
[B]. As a result, reagent-saturated air is sucked into the reaction
tube, raising the pH of the sample to a value of 10.5, and forming a
regular stream of air bubbles [J].
The bubble stream is used to monitor the correct sample flow with
the bubble detector [I]. An inconsistent sample flow causes an inter-
ruption of the bubble formation and produces a system error.
If the automatic regeneration module [P] is installed, the solenoid
valve [Q] opens at configurable intervals, which automatically etches
(i.e. regenerates) the sodium sensor.

Second
Sample Stream
If required the AMI Sodium P can be equipped with the optional sec-
ond sample stream module. To install the 2nd sample stream option,
an AMI Sodium P with 400 mm or 375 mm panel width is required.
Sample
Sequencer
If measurement of more than two sample streams is required, the
AMI Sodium P can be connected to a Sample Sequencer, which al-
lows to measure up to six sample streams.
Automatic
Regeneration
Optionally, the AMI Sodium P can be equipped with a module for
automatic sensor regeneration. To install the automatic regeneration
module, an AMI Sodium P with 400 mm panel width is required.
Grab Sample The standard bottle holder can also be used for a grab sample mea-
surement. For details, see Grab Sample, p. 58.
Calibration A standard bottle is screwed in the standard bottle holder [Q] and
turned upwards into the vertical position, thus switching the sample
flow from the constant head to the standard bottle. Constant pres-
sure within the standard bottle is maintained by the pressure-equaliz-
ing tube inside the bottle.
One liter of standard is consumed in approx. 10 min. The sodium
electrode must reach constant readings within this time to obtain an
exact calibration.
For details, see Calibration, p. 42.
Consumables The filling of the 100 ml KCl bottle lasts for one month of operation.
