Key FeaturesTechnical SpecificationsApplications

680 °C catalytic combustion oxidation technology for efficient oxidation of a broad spectrum of organic compounds, including easily-decomposed low-molecular-weight organic compounds and hard-to-decompose insoluble and macromolecular organic compounds.
Ultra-wide measurement range from 4 μg/L to 30,000 mg/L, enabling analysis of both ultrapure water and heavily contaminated samples.
Reliable sample injection system designed to ensure stable and reproducible analytical performance.
Automatic sample acidification and sparging to simplify analysis of non-purgeable organic carbon (NPOC).
Automatic dilution function that helps reduce the effects of high salinity, acidity, and alkalinity while extending the service life of catalysts and combustion tubes.
Flexible sample scheduling, allowing priority samples to be added during operation without interrupting ongoing analyses when an autosampler is used.
PC-controlled operation for streamlined instrument control, data management, and workflow automation.
