multi N/C series – the family of instruments sets standards!

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 TN_b 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, e. g., TOC determination in sewage sludge or soils.

Working with the multi N/C series analyzers guarantees compliance with the valid national and international standards, such as: ISO, EN, DIN, EPA, ASTM, USP, FDA and pharmacopoeias.

Your advantages at a glance

multi N/C 2100

The multi N/C 2100 is the space-saving TOC/TN_b analyzer which demonstrates its strength particularly in the field of environmental analysis. Along with VITA, the FR NDIR detector and catalytic high temperature combustion up to 950 °C, multi N/C 2100 is equipped with a perfect injection technique for particle containing samples. The integrated autosampler and the solid technique turn it into a compact routine analyzer.

Characteristics of multi N/C 2100 and multi N/C 2100 S

multi N/C 3100

No matter whether ultra-pure water or waste water, multi N/C 3100 is suitable for all liquid samples. This is made possible by the combination of catalytic high-temperature combustion, VITA, the Focus Radiation NDIR Detector, as well as flow injection with intelligent rinsing technology for particle-containing samples. In addition, multi N/C 3100 is particularly fast and thus permits high sample throughputs.

Charakteristics of multi N/C 3100: 

multi N/C UV HS

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 an 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.

TOC determination made easy!

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.

multi N/C pharma HT

Pharmaceutical applications require special technological solutions: highest sensitivity and precision as well as adaptation to the requirements of the pharmaceutical industry.

Depending on the application, two digestion principles are available:

• multi N/C pharma HT: catalytic high-temperature combustion up to 950 °C
• multi N/C pharma UV: wet chemical oxidation in a High Power UV reactor

Designed for the pharmaceutical industry!

For both digestion principles the focus is on the precision and correctness of the measurement results in the lower measurement range.

This is possible thanks to the VITA Flow Management System and by high sample injection volumes with the help of a high-precision injection syringe. And also by the use of a volume-specific calibration method which can be used to perform reliable calibration down to the lower ppb range. Minimal system blank values are obtained through the automatic purging of the used chemicals. In addition, a blank value free digestion without reagents is available.

multiX^® 2500

In environmental monitoring as well as in process and quality control, the determination of organic halogens which can be adsorbed by activated charcoal is very important for the evaluation of water and waste water. With the multi X^® 2500, Analytik Jena provides a flexible, future-oriented system for sum parameter analysis that meets the requirements of every modern laboratory.

AOX/TOX/EOX/POX/TX analysis

Thanks to the innovative double furnace technology and the proven gas lock for sample introduction multi X^® 2500 is a completely new generation of AOX analyzers.

Double furnace technology

The innovative double furnace technology with tilting furnace combines the advantages of both the vertical and horizontal furnace into one analysis system. A design that sets standards.

High degree of operator convenience due to

The fully automated autoX samplers are available in a variety of versions and with different capacity.
