Product Details

TOC and TNb analysis for each application

From surface and waste water investigations in the environmental sector, to high-purity water in the semiconductor or pharmaceutical industry – our multi N/C instruments offer you customized solutions for reliable TOC/TNb measurements in your field of application. When it comes to difficult sample matrices, the multi N/C series excels due to their reliability and ease of maintenance. With the new multi N/C duo systems, we now also offer combined analytical instruments for fully automated liquid and solid TOC analysis.

The multi N/C series complies with 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 TOC and TNb analysis requirements

At the heart of each model in the multi N/C series is the corrosion-free Focus-Radiation NDIR detector. Across 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 the EasyCal feature enables 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, enabling blank value-free analysis without oxidizing agents. Furthermore, numerous liquid and solid automation options, nitrogen detectors, and solid modules are available.

What Our Customers Say

Easy maintenance, high throughput with NPOC

“The equipment can be very easily maintained, and maintenance costs can be kept to a minimum. Through the automatic acidification function, 40 or more samples can be acidified at once to perform analysis using the NPOC method.“

Da-Ae Choi, Senior Researcher at Seongnam Water Restoration Center, Korea 



"This instrument is robust – a real lab routine mainstay"

"The instrument is ideally suited for the analysis of all types of water – from ultrapure and drinking water to industrial waste water. The multi N/C 3100 is robust and a real lab routine mainstay. The short reaction times and the excellent cooperation with regular representatives are not only of assistance to my laboratory, but to me personally as well."

Dr. Ralph Zimmer, Lead Analytical Manager Dow Böhlen#
