And more than two billion people live in countries where the water supply is permanently inadequate. Often these are regions with high water pollution. At the same time, awareness of health issues is steadily increasing worldwide. These aspects are leading to ever increasing demands for good water quality.

To ensure that water is of good quality, it must be permanently monitored. This is achieved by means of sensors. An important indicator of water quality is its total organic carbon (TOC) level. Consequently, in the future TOC sensors will make a significant contribution to achieving better water quality in various markets and applications, such as in appliances, waterworks and bioreactors.
