Online Toximeter for Drinking Water and Surface Water Monitoring.

LAR's toxicity analyser ToxAlarm continually monitors drinking and surface water for pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria. The measurements follow at itervals of less than 5 minutes even after events of toxicity.

The bacteria are self-reproducing. In this case a huge advantage.

ToxAlarm contains a bacteria culture, which constantly and independently produces Biomass. This means that there is always enough bacteria for each new measurement. Furthermore, the risk of the fermenter being contaminated is removed because every water sample is tested with a fresh amount of bacteria.

Robust toxicity analyser. Sensitive test organisms.

The bacteria are extremely sensitive to a multitude of toxins. Through their reaction to the harmful substances in the water sample, toxicity can be reliably determined. For example, a reaction already starts at a cyanide concentration of less than 0.10 mg/litre.

Reduced maintenance. No further purchases necessary.

Firstly, it is not necessary to purchase or externally cultivate test organisms, such as fish or daphnia. Secondly, the toxicity analyser is extremely low in maintenance because the bacteria mass constantly proliferates on its own.

The nitrification respiration inhibition test. Simpler than its name.

The bacteria live on (consume) oxygen from the conversion of ammonia to nitrate, which is why they are described as nitrifiers. ToxAlarm measures this oxygen consumption. Toxic substances in the sample contents inhibit the respiration of the bacteria, thus lowering their oxygen consumption. The ToxAlarm monitors this oxygen consumption and hence the toxicity.
