High performance and low maintenance are properties which set apart the new generation of TOC instruments working on the UV-supported wet chemical digestion principle from Analytik Jena (Germany). The multi N/C UV HS – an ideal TOC instrument for ultra-pure water, drinking water, groundwater and low-particle wastewater. The extreme performance of the technique is achieved through the use of two different wavelengths. In addition to conventional UV radiation at 254 nm, a highly efficient wavelength of 185 nm is used for sample digestion.

The sample to be analyzed is located in a special reactor from Analytik Jena, which is directly surrounded by the relevant radiation source. This achieves a very high radiation density and therefore very high digestion of the contents of relevance to TOC. The optional addition of an oxidation agent alongside the “normal” UV radiation serves to further optimize digestion, especially of highly-polluted samples.

The user is guaranteed a high level of cost-effectiveness thanks to the low maintenance requirement and long service life of the UV lamp is achieved with special reaction engineering. The troublesome formation of ozone is safely avoided through the use of nitrogen as the carrier gas.

Analytik Jena’s multi N/C UV HS can be used for the most varied applications as a result of its flexibly variable sample volumes (0.5 ml – 20 ml) and its special multi-channel NDIR detector. The system can also be equipped with the appropriate sampler and a high temperature module depending on the type of application.
