• The TOC measuring principle of the enviro TOC is based on catalytic high-temperature combustion of the sample in an oxygen stream (for liquid – 850°C & for solid – 950°C).

        • 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 only a few minutes.

        1) Pure Samples: Samples should be free of contamination.

        2) Sample Volume/Weight:
            Liquids: 50–60 ml for water samples.
            Solids: 0.1–1.0 gm finely ground or powdered.

        3) Handling: Ensure uniform consistency for liquids and filtration if necessary.

        • Environmental Monitoring: Environmental monitoring (e.g., water quality in lakes, rivers).
        • Wastewater Treatment: Wastewater treatment processes and management.
        • Drinking Water Analysis: Analysis of drinking water for safety and compliance.
        • Industrial Applications: Industrial applications (e.g., pharmaceuticals, chemicals).
        • Research and Quality Control: For research and quality control purposes.
