Conclusion
Using the previously described sensor system expanded with the FIA
system, and in a miniaturised configuration, hydrogen peroxide concentra-
tions of 5 ¥ 10
-4
mol l
-1
to 2 mol l
-1
can be determined over the complete pH
area. Obviously, the FIA setup is incorporated only if the pH is lower than
ca. 10.5. When the pH is higher than 10.5, the classic flow-tube system can
be used, which is faster, simpler and cheaper, unless the hydrogen peroxide
concentration to be determined is so low that it cannot be detected with,
for example, a pH of 10.5, but instead requiring a pH of 12.5. Expanding
the sensor with a FIA system can also be considered in such applications.
