Product Features
1. Automatic valveless micro-injection pump; the sample injection volume can be adjusted according to the sample measurement list to achieve different injection volumes.
2. Precision pipeline design with no dead volume, ensuring easy cleaning of the piping system.
3. High-temperature catalytic furnace: different catalysts can be configured according to the specific sample, and the temperature can be set within a range of 680–900°C.
4. An inorganic carbon reaction unit with heating and temperature control eliminates peak tailing, shortens sample analysis time, and ensures the reproducibility of measurement results.
5. Two-stage electronic refrigeration dehumidification, coupled with liquid-level monitoring, effectively safeguards the integrity of the detection unit.
6. Polymer membrane dehydration reduces the dew point of the sample gas entering the detector, thereby enhancing detection accuracy.
6. Optionally equipped with a 24-position autosampler for unattended operation, saving labor and time.
7. Optional solid-sample injection module for measuring solid and semi-solid samples.
8. The detector’s gas chamber features an electroplated, high-infrared-reflectivity metal inner wall, which minimizes infrared light loss and ensures high detection accuracy.
9. Front-mounted combustion chamber design for convenient operation and maintenance.
10. The detector employs 24-bit A/D conversion technology, resulting in more stable data, lower noise, a wider detection range, and faster response.
11. The unique long-tube halogen removal unit effectively eliminates the interference of halogens on the detection results and protects the detector.
12. Scalable total nitrogen detector for measuring total nitrogen
13. The standalone instrument offers two oxidation modes: high-temperature combustion and UV persulfate oxidation; the UV persulfate oxidation mode allows for a larger injection volume and achieves a lower detection limit.
14. Complies with the international standard ISO 8245, the National Environmental Protection Standard of the People’s Republic of China HJ 501-2009, and the National Metrological Verification Procedure of the People’s Republic of China JJG 821-2005.
