TOC and TNb analysis for each application

From surface and wastewater investigations in the environmental sector to high-purity water in the semiconductor or pharmaceutical industry - our multi N/C instruments offer you tailor-made solutions for reliable TOC/TNb measurements in your field of application. Especially in the case of difficult sample matrices, the devices are convincing due to their reliability and ease of maintenance.

With the devices of the multi N/C series, you work in compliance to the valid standards and with the devices of the pharma series to the FDA/GMP guidelines. The devices guarantee maximum operating time and low running costs. Analytik Jena offers a ten-year warranty on the NDIR detector and on the furnace technology of combustion-based multi N/C models and a three-year warranty on the UV reactor for UV-based multi N/C models.

Sophisticated technologies for your analysis

At the heart of every model in the multi N/C series is the corrosion-free Focus-Radiation-NDIR detector. Over a measuring range from 0 to 30,000 mg/l TOC it achieves the highest sensitivity and precision without sample dilution. The VITA flow management system effectively compensates for carrier gas fluctuations and enables with EasyCal automatic and long-term stable calibration.

Two sample digestion methods are available for TOC measurement: high-temperature combustion up to 950 °C and wet chemical UV oxidation. The high-power long-life UV reactor uses two wavelengths (185/254 nm) for complete oxidation, even blank value-free analysis without an oxidizing agent is possible. Furthermore, numerous automation options, nitrogen detectors and solid modules are available.
