Turbidity describes the cloudiness of a liquid caused by suspended particles. It is an important quality parameter in numerous chemical, environmental, and industrial applications.

Turbidity results from the scattering of light by solid or liquid particles within the sample. The higher the particle concentration, the greater the turbidity of the liquid.

In analytical laboratories, turbidity is frequently used to monitor filtration processes, digestion procedures, or the quality of liquid samples. Increased turbidity can indicate incomplete digestion or insufficient removal of particles, thereby compromising the reliability of subsequent analyses.

With the PrepMaster Vision – Turbidity Module, HERZOG has developed a fully automated solution for determining turbidity. After digestion, the module independently checks the quality of the liquid sample and assesses whether it meets the defined requirements for subsequent analysis. This eliminates the manual visual inspection by a lab technician that is otherwise often necessary before transferring the sample to the analyzer. This enables a fully automated sample flow from digestion to analysis, improves the reproducibility of quality assessment, and increases sample throughput in automated wet chemistry laboratories.
