TOXcontrol – Toxicity Monitoring System

It still is not possible to use the traditional chemical analyses alone to get a complete view of the water quality. 

The most important reasons why to use On-line biomonitoring systems are:

• Traditional analyses are only possible for a  small number of the dangerous  chemical substances, even with the latest highly sophisticated instruments.
• It is estimated that only about 5% of the existing toxic chemicals in water can be analysed by on-line monitors.
• Concentrations of many products are lower then the detection limits.
• Results of traditional, chemical analyses give no information regarding the  toxicity of the combined effects of mixtures.

Toxicity monitoring with Luminescence bacteria
Advantages of the TOXcontrol:

• Easy to operate, user-friendly and very robust.

• Very reliable, low running & maintenance cost.

• Automatic cultivation of bacteria in the TOXbioshaker.

• TOXview software for data acquisition & evaluation.

• Can be used with in-line dechlorination.

• Optional uv-vis sensor (TOX-s::can) for TOC, BOD, turbidity, SAC254, NO3-N

This completely automated Biomonitoring System uses freshly cultivated light emitting bacteria (Vibrio fischeri) as a biological sensor. The luminescence is measured before and after exposure to calculate the inhibition in %.

The luminescent bacteria test is an automated version of the ISO 11348 allowing continuous monitoring of rivers, drinking water  production or wastewater treatment plants.
