Facility Description
Estimation of Total Organic Carbon (TOC) in water, solid, and other samples, and Bound Nitrogen (TNb at ppm level)
The TOC measuring principle of the enviro TOC is based on catalytic high-temperature combustion of the sample in an oxygen stream (for liquid-8500C & for Solid-9500C).
Under these conditions, all bound and dissolved carbon is oxidized to CO2, which is determined quantitatively with an IR detector.
Sample pre treatment steps, e.g. for removing the inorganic carbon from the sample, are fully automated. The TOC analysis provides easily evaluable results since matrix effects are negligible and the carbon concentration in the sample correlates linearly with the CO2 signal.
In comparison to other techniques for the determination of organic contamination, the use of hazardous substances is avoided and the analysis time is a few minutes.
