Success Story“The multi N/C® 3100 is well suited for the analysis of all kinds of water –from ultrapure and drinking water through to industrial waste water. This
is not a great challenge for the instrument even if the water samples havea high level of salt or particles. The instrument is robust and holds up toeveryday use.”

Active around the world, the Dow Chemical Company (Dow)has been employing Analytik Jena AG instruments for thepast 15 years. Founded in 1897, Dow is one of the world’s
leading manufacturers of basic and special chemicals and highperformance materials. Based in Midland, Michigan, it is one of the ten largest U.S.
companies in Germany. Dow has also been active in Central Germany since 1995,
continuing the region’s strong tradition in plastics and chemical manufacturing at sites
in Schkopau, Böhlen, Leuna, and Teutschenthal.

At Dow, one important basis of support when it comes to upholding environmental
protection standards is the TOC analyzer multi N/C® 3100. The company uses theanalysis system to examine waste water for the presence of contaminants. And twoparameters are particularly important in the process of examining water quality: Organic
contamination as quantified by the determination of total organic carbon (TOC) andcontamination with nitrates, nitrites, ammonium salts, and organic nitrogen compounds,
as represented as total nitrogen bound (TNb). Both parameters can be determinedeasily and rapidly using the Analytik Jena multi N/C® 3100.

Determining two parameters at once
The water sample is injected into a high-temperature reactor. All the carbon compounds
are rapidly converted to carbon dioxide at approx. 800 °C, with a catalyst supporting
the oxidation process. The carbon dioxide thus created is analyzed and quantified using
a non-dispersive infrared sensor (NDIR). The nitrogen compounds in the water sample
are converted into nitric oxide in the high-temperature catalytic oxidation process,with the support of a chemiluminescence procedure. This makes it possible to determine
both TOC and TNb from a single sample injection. As Dr. Ralph Zimmer, lead analyticalmanager at Dow´s Böhlen site, explains: “The instrument is well suited for the analysis

A self-checking hardware and software system ensures that the device provides reliable
results around the clock. The system examines everything from gas flow to detector
status. Gas leaks and flow fluctuations are thus noticed immediately and scatteredresults and false low readings are eliminated. This reliability and robustness are uniqueselling points on the analytical measuring technology market. Such a low-maintenancesystem that holds up to everyday industrial use was, however, not a matter of chance:
Analytik Jena and Dow work closely together so that the wishes and experience of thetechnicians can be taken straight into account in the developmental process.

“Most effective technologies”
It all began with a leap of faith: When Dow placed its first order with Analytik Jena
before the turn of the century, Analytik Jena had just begun to gain traction in its firstmarkets. The products and technologies of the new company, whose founders emerged
from the formerly state-owned VEB Carl Zeiss Jena, were, however, an immediate
success. Analytik Jena is now an established company and the companies of the Dow
Group make use of analytical measuring technology from Jena at their sites all aroundthe world in places such as Spain, the Netherlands, the United States, Thailand, andKuwait. Products from the Analytik Jena portfolio can be found on Dow’s list of mosteffective technologies. As Dr. Ralph Zimmer explains: “Short reaction times and theexcellent cooperation with regular contact people are not only a great help for my lab
but for me personally as well.”
