Product Details

Working Principle

Through a high-performance oxidation catalyst in the combustion furnace, the sample is completely combusted at high temperature into CO₂ and water vapor. Water vapor is removed by a condenser, and CO₂ is measured by a non-dispersive infrared (NDIR) detector to determine total carbon (TC). Inorganic carbon is decomposed by acid reagent into CO₂ and water; after condensation, CO₂ is measured by NDIR to determine total inorganic carbon (TIC). TOC = TC – TIC.

Applications

Tap water, surface water, rivers, lakes
Domestic sewage, industrial wastewater
Chemical process water (cleaning water, cooling water, recycled water, etc.)
Laboratory research

Standards

ISO 8245
China National Environmental Protection Standard HJ 501-2009
China National Metrological Verification Regulation JJG 821-2005

Software Description

The software meets GMP computerized system validation requirements:
Electronic signature: unique login with username/password, password length requirement, manual screen lock.
Access control: multilevel permissions; administrator assigns roles.
Data integrity: audit trail (non-disableable), all results saved and non-modifiable, all operations recorded, method-change logging, and data export/backup.

Features

High-performance detection: gold-plated gas cell, high-concentration IR source, and high-sensitivity IR detector for excellent NDIR performance at ppb level; real-time curve display.
High-efficiency oxidation: furnace up to 1300 °C (far above conventional 680 °C), enhancing oxidation efficiency for almost all substances, improving accuracy and stability; multi-protection heating with automatic cut-off.
Flexible experimental conditions: choice of catalysts (CeO, Pt, CuO) and adjustable temperature for versatile testing.
Advanced dehydration and injection: three-pass electronic condensation and automatic liquid injection with a precision electromagnetic metering pump for accuracy, stability, and continuous uniform injection. Non-manual injection reduces human contact with liquids.
Extended capability: heated inorganic carbon reactor eliminates peak tailing; optional solid sampler for soil, sludge, etc.
Real-time monitoring & data management: multiple temperature, pressure, and flow self-monitoring; a built-in needle printer; 2-year data storage with time-based query; and password protection.
Optional modules: online monitoring module; automatic sampler for unattended operation.
User interface: high-resolution 10.4-inch touch screen.
