Facility Features, Working Principle, and Specifications:

• Features:

  • High-sensitivity analysis of total organic carbon in aqueous samples.

  • Modular design with options for total nitrogen (TN) measurement.

  • Autosampler compatibility for high-throughput analysis.

  • User-friendly software for data management and compliance.

• Working Principle:

  • Uses the 680°C catalytic combustion oxidation method to convert organic carbon to CO2, which is measured by a nondispersive infrared (NDIR) detector. The system can measure total carbon (TC), inorganic carbon (IC), and non-purgeable organic carbon (NPOC).

• Body Specification:

  • Detection range: Typically 4 µg/L to 30,000 mg/L (depending on configuration).

  • Compact design with high-precision injection system.

  • Optional TN module for simultaneous nitrogen analysis.

• Applications:

  • Water quality analysis (e.g., drinking water, wastewater).

  • Pharmaceutical cleaning validation.

  • Environmental monitoring of organic pollutants.
