1.3. Restrictions for use
The sample must not contain any particles, which may block the
flow cell. Sufficient sample flow is coercive for the correct function
of the instrument.
If the sample contains only little disinfectant concentrations, or
there is the danger of biological growth, we recommend to use the
optional Cleaning module from Swan which is available as an option for the AMI Phosphate-II.
WARNING
For safe instrument installation and operation you must read
and understand the instructions in this manual, as well as the

2. Product Description
Application This manual describes the functions of the analyzers:
AMI Phosphate-II
AMI Phosphate-II B
Both analyzers are complete monitoring systems for the automatic
continuous measurement of ortho-Phosphate. ortho-Phosphate
can be found in many applications like corrosion protection in sanitary systems and boilers or as additive to detergents. On-line measurement is used in quality control of drinking water, waste water
plants and thermal power plants.

The measurement is based on the molybdenum blue colorimetric
method according to APHA 4500-P E. and on EN ISO 6878. When
the reaction product of o-phosphate with ammonium-molybdate is
reduced with ascorbic acid, the intensely colored molybdenum blue
is formed. The color intensity is proportional to the o-phosphate
concentration of the sample and is measured photometrically at
815 nm.
The duration of a measuring interval can be set to:
10 min (not available if “2 Channels” is selected)
15 min
20 min
30 min
Independent of the programmed measuring interval, the measurement time of a sample takes 7 minutes.
Two signal outputs programmable for measured values (freely scalable, linear or bilinear) or as continuous control output (control parameters programmable).

Product Description
On-line
operation
Calibration Close the flow regulating valve to drain the constant head. Prepare
The sample flows through the sample inlet [K] and the filter vessel
[J] into the constant head [A]. Adjust the flow regulating valve so
that always a small part of the sample flows through the overflow
tube [B] into the drain [R]. This adjustment ensures a sufficient
sample flow through the measuring chamber of the photometer [M].
If no measurement takes place, the sample flows through the outlet
of the photometer where it will be aerated through air inlet [H] to
generate bubbles. Then the sample flows through the bubble counter [P] into the waste [Q].
If a measuring cycle starts:
1 A zero measurement with the sample is performed before the
reagents are added.
2 The peristaltic pump [C] pumps the reagents [N] and [O] into the
mixing chamber [G] where they are mixed together with the
sample and then flowing through the photometer [M].
3 The solenoid valve [I] will be activated to close the inlet of the
photometer.
4 The sample remains in the photometer for 7 minutes. During
this time a reaction with the reagents takes place.
5 After the 7 min have elapsed a second measurement is carried
out and the o-phosphate concentration is calculated.
6 If the measurement has been finished, the solenoid valve will be
deactivated to open the inlet of the photometer.
7 The sample flows through the outlet of the photometer where it
will be aerated to generate bubbles.
8 The sample flows through the bubble detector [P] and into the
waste [Q].

head. A normal measuring cycle is then initialized, the measured
value is used to calculate the photometer's slope. For details see
