Amperometric method of determining the specific inhibition
effect of the substances contained in a sample on ammonia
oxidation in
connection with microbial nitrification with the aid of
defined bacterial strains, preferably of the genus Nitrosomonas.
The results are specified as % inhibition of oxygen consumption
in the sample solution in comparison to a non-inhibited
control solution.
N-TOX
Amperometric
method of determining the specific retardation effect of
the substances contained in a sample on nitrite oxidation
in connection with microbial nitrification with the aid
of defined bacterial strains, preferably of the genus Nitrobacter.
The results are specified as % retardation of oxygen consumption
in the sample solution in comparison to a non-inhibited
control solution.
BioFix®Lumi-10
BioFix®Lumi-10
is a portable luminometer for the measurement of biological
and chemical luminescence reactions with relatively constant
light emission. As a mobile test system with a high sensitive
detector (Ultra Fast Single Photon Counter) the BioFix®
Lumi-10 is suitable for a wide range of applications.

Sludge
Activity Tests
Determination
of the biochemical activity of sludge (activated sludge,
digested sludge etc.) by means of the dehydrogenase activity
using 2,3,5-Triphenyltetrazoliumchloride (TTC).
Colourless TTC is converted into red triphenylformazane
(TPF) by dehydrogenases. The formed, water insoluble TPF
is dissolved in ethanol and is photometrically determined.
