Direct δ13C isotope analysis of TOC in aqueous samples
The iso TOC cube is a combustion analyzer with greater analytical robustness and less maintenance than analyzers working with wet-chemical or UV oxidation methods. Even when analyzing refractory organic substances such as humic acids or lignin, which are traditionally difficult to combust, you can expect reliable, matrix-independent measurement results thanks to the complete conversion of all compounds at these high combustion temperatures. Thus, the iso TOC cube enables dissolved carbon and nitrogen isotope ratio analysis with highest precision and accuracy in all types of liquids, from drinking water or industrial wastewater up to soil leachates, suspensions, brines, or marine samples. For low TOC samples the iso TOC can be configured with an optional column, which preconcentrates TOC.
