For the automation of the evaluation of kinetic data, we have built up
a modular laboratory unit with three different continuously working g
radientless reactors (CSTR, double-mixed-contactor, berty-reactor). Th
e experimental plan and the laboratory unit are controlled by a proces
s-control-system. In the CSTR we have determined kinetic data for a th
ree-phase enzymatic reaction. The NO-absorption was part of our resarc
h in the double-mixed-contactor. The results of our investigation and
the problem of automation are the content of this paper.
