Mercury determination in drinking and waste waters is one of the most popular analyses used for environment pollution and sanitary control, as this trace element is considered highly toxic.

Many conventional methods of mercury determination in water use cold-vapor atomic absorption spectrometry (CVAAS) technique. As an alternative, Lumex Instruments proposes the thermal decomposition method for direct analysis of all kinds of water and aqueous solutions using RA-915 Lab mercury analyzer. Unlike CVAAS, it does not require high-purity reagents, preliminary digestion of the sample, thorough laboratory preparation, and other costly and time-consuming procedures.
