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. Especially in the case of difficult sample matrices, the devices are convincing 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.
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 each model of 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 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, enabling blank value-free analysis without oxidizing agent. Furthermore, numerous liquid and solid automation options, nitrogen detectors and solid modules are available.

What Our Customers Say
"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
Easy maintenance, high througput 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.“
