Design and Function
4.7 Enzyme Reactor Function
The enzyme reactor is required for measuring
methanol and ethanol. Inside the reactor is the
immobilized enzyme alcohol oxidase (AOD).
There, the corresponding alcohol is converted
and hydrogen peroxide is formed. The hydrogen
peroxide is then detected in the conductivity cell.
CAUTION
High temperatures can destroy the enzyme!
Due to the stability of the enzyme used, the
ambient temperature may not exceed 25 °C.
Athigher temperatures, it is obligatory to use a
climatic chamber.
4.8 Temperature Correction
The BioPAT
®
Trace | Multi Trace is equipped with
a temperature sensor. This is arranged in the
proximity of the conductivity cell. All measured
values are corrected by using a temperature-
dependent function.
