Overview
The document discusses the importance of online analysis of Total Organic Carbon (TOC) and Total Nitrogen (TN) in industrial processing, particularly in cooling water circuits and water/wastewater technology. It highlights the increasing significance of these parameters for accurate and continuous monitoring.
Specifications
The TOC and TN-4110 series analyzers offer simultaneous measurement of TOC and TN using catalytic combustion oxidation/NDIR detection for TOC and combustion/chemiluminescence detection for TN. The TOC-4110 can measure up to 20,000 mg/L, while the TN-4110 covers a range from 1 mg/L to 4,000 mg/L.
Integrated Sample Pre-treatment System
The system features a unique sample injection mechanism with a sliding valve and high-precision syringe. It supports automatic calibration with internal standard solutions and includes an offline measurement port for external samples. The dilution function aids in handling high concentrations and salt levels.
Automation and Control
The analyzers can be operated and calibrated remotely, with multiple sample streams selectable. They include alarm and status signals for maintenance alerts and limit exceedance detection. Automatic dilution and calibration checks enhance automation.
Sampling UnitsVarious sampling units are available to optimize sample collection, including:
- Backwash Strainer Unit: Effective for homogeneous samples, uses compressed air for cleaning.
- Single Stream Unit: Cost-effective, homogenizes samples, and uses tap water for rinsing.
- Multi-stream Unit: Allows measurement of up to six sample streams, with individual program selection and rinsing to prevent carry-over.
Technical Features
The document includes diagrams illustrating the flow and components of the sampling and analysis process, emphasizing the compact design and high performance of the analyzers.
