Water and environmental analysis
Precise Measurement Results and Environmentally Compatible Methods optimize our Devices for the use in Environmental Analysis.
The content of total organic carbon (TOC) in water and solid samples is one of the most important screening parameter in environmental analysis. Whether you look at the evaluation of water quality or at the recycling of residues – there is no way around TOC.
TOC analyzers: More than 40 years experience in environmental and water analysis
For decades users in environmental and water analysis rely on TOC analyzers by Elementar. The whole spectrum ranging from ultrapure water, waste water to sludges and solids is covered by a single flexible TOC analyzer. In addition to the determination of TOC, the content of total bound nitrogen (TNb) can also be determined simultaneously in aqueous samples. Even difficult samples like sea water and concentrated chemicals and acids are no longer a challenge. The measuring range extends from a lower detection limit of 3 µg/l (vario TOC cube) up to 100,000 mg/l (vario TOC select).
Reliable TOC analysis through effective sample digestion
By a real catalytic high temperature digestion of 850 °C, the complete oxidation of TOC is ensured. To guarantee such a temperature over a long interval, the catalyst is protected from detrimental factors such as salts through a special, patented process at Elementar. Already during the design of the TOC analyzer emphasis is put on easy accessibility of all parts that require a regular maintenance. The exchange of combustion and adsorption tubes is a matter of a few minutes only.
Fully automated TOC analysis in water and solids
There is no need to mention that the analysis of water is performed fully automatically. But also solids can be analyzed for TOC through automatic sample feeding. Just weigh the sample in tin capsules, seal the capsule and put it on the sample tray - that’s it. Even the change from liquid to solid mode can be performed in max. 5 minutes. Analysis times of 3 to 4 minutes turn Elementar’s TOC analyzers into work horses for routine operation in environmental and water analysis.
