C and N analysis in aqueous samples
The Multi N/C 3100 Analyzer has been designed for the determination of carbon and nitrogen content in aqueous samples. This determination is carried out by thermocatalytic decomposition. Thermocatalytic oxidation at 950°C allows the quantitative determination of even poorly oxidizable carbon and nitrogen components in water and water samples with a high particle content or very saline water.
