Chapter 1 : Introduction
1.1 Introduction
The SODIMAT - Model 9073 permits the
measurement of sodium in industrial
ultrapure waters.
The measurement is based on a direct
potentiometric technique using a highly
sensitive sodium glass electrode. The
difference of potential between the glass
electrode and the reference electrode is
directly proportional to the sodium
concentration as shown by the Nernst law:
1.2 Applications
Modern high-pressure power plants require
feedwater of very high purity. Safety in that
sector is of great importance and the
sodium measurement plays a specific role
compared to pH, conductivity and silica
trace.
Actually, sodium cations and anions are
always linked. Most cations have a
corrosive influence in water and vapor
cooling circuits.
Because of this chemical link between
sodium ions and anions, sodium
measurement presents particularly
important risks of corrosion and other
effects.
The presence of chlorides, for example,
involves corrosion under power and when it
exceeds allowable concentration limits.
