Swann AMI CACE - Restriction for Use

AMI CACE
Safety Instructions
A-96.250.871 / 120417 7
1.3. Restriction for use
The AMI CACE is designed for determination of:
 specific (total) conductivity
 cation (acid) c
onductivity after the cation exchanger (CACE)
in power plant water.
It calculates the pH value and the concentration of the alkaline sub-
stance (NH
3
, morpholine, etc.) if an alkaline substance is present in
the water.
It is not suitable for pH determination in high purity water before
alkalization agent addition.
Conditions for pH calculation:
 only 1 alkalization agent in the sample
 the contamination is mostly NaCl
 phosphate concentration is < 0.5 ppm
 pH value is > 7.5, and < 11.5
 if pH value is < 8, the concentration of contaminant must be
small compared to the concentration of the alkalization agent
No sand. No oil. Use of film forming products may reduce lifetime of
EDI module.
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.
