multi N/C® UV HS – TOC determination made easy!

The multi N/C® series is the powerful family of instruments with a convincing overall concept for the fully automatic and simultaneous analysis of the parameters TOC, NPOC, POC, TC, TIC und TNb in liquid samples.

multi N/C® offers the optimum solution for every application. From the analysis of drinking water and waste water, pharmaceutically used water or cleaning validation, surface water, through to water in power plants or in the semiconductor industry or solid substance analysis.

The multi N/C® UV HS is a wet chemical TOC analyzer which works both with an oxidation agent (peroxodisulfate) and a highly effective UV radiation source for sample oxidation. At the same time the system is highly sensitive and suitable – along with ultra-pure water samples – also for drinking water or special samples, such as acids, electrolysis baths and other aggressive matrices.

Unlike classical TOC analyzers with a UV reactor, multi N/C® UV HS uses two wavelengths instead of just one: 254 nm and 185 nm. The hard radiation obtained in this way guarantees a complete oxidation of even the most stable carbon compounds. The effective blank value reduction by means of automated purging of the reagents ensures minimal system blank values.

For ultra-pure water analyses a suitable method can be selected in the user interface, so that the High-Power UV reactor delivers the necessary energy for complete oxidation without oxidation agents. Thus, the blank value of the oxidation agent can not cause interference in the trace analysis – even in complicated matrices.

The core element of the multi N/C® series models is the new Focus Radiation NDIR Detector® equipped with high-quality optics for precise detection of CO2. Energy-rich radiation is focused onto the microdetector with the help of integrated optics. The radiation density obtained in this way surpasses classical detectors many times. This results in higher sensitivity and precision over a wider measurement range.

Analytik Jena is the only manufacturer to gladly grant all customers a long-term warranty of 10 years for the Focus Radiation NDIR Detector®.
