Product Description
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 exchangers, condenser leaks and the prevention of caustic corrosion
of turbines. 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
Signal
Outputs
Relay Two potential-free contacts programmable as limit switches for
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 temperature compensation curves.
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 0.1 ppb
sodium requires the conditioning of the sample to a minimum of
pH 10.5 while sample integrity has to be maintained. The best results are obtained with Diisopropylamine (DIPA).
Two signal outputs programmable for measured values (freely scalable, linear or bilinear) or as continuous control output (control parameters programmable).

The sample flows via the sample inlet [D] and the flow regulating
valve [C] into the constant head [A]. 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 [K
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 [Q] 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 interruption of the bubble formation and produces a system error.

Result
When starting the calibration, you first have to perform the pH-Calibration and then the Sodium calibration! The Sodium measurement
is dependent on the pH value.
6.10.1 pH Process Calibration
You need a high quality pH meter to do the correction. We recommend to use the SWAN Chematest 25. The hand held pH meter
must be calibrated correctly!
Navigate to menu <Maintenance>/<Calibration>/<Process pH>.
The signal outputs and alarms are on hold.
1 Stop the sample flow by swinging the standard bottle holder
halfway upwards.
2 Take the sodium electrode out of the flow cell and insert the pH
electrode of your hand held pH meter instead.
3 Wait until the value of your instrument is stable.

Program List and Explanations
As control out-
put
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
