ConductScience UV Wet Oxidation TOC Analyzer — NDIR Detection, 5 ppb LOD

UV Wet Chemical Oxidation TOC Analyzer with NDIR Detection

This TOC analyzer combines UV wet chemical oxidation with NDIR detection to achieve an exceptional 5 ppb detection limit while maintaining a wide 0-10,000 mg/L measurement range. It provides the sensitivity needed for purified water analysis with the robustness to handle environmental and process water samples, measuring TC, TIC, TOC, and NPOC parameters.

Applications

• Pharmaceutical and biotechnology water system monitoring
• Environmental water quality analysis
• Municipal drinking water treatment verification
• Laboratory research on organic carbon dynamics
• Food and beverage process water testing
• Semiconductor and electronics ultrapure water analysis

Key Features

• UV Wet Chemical Oxidation: Combines UV radiation with persulfate reagent for thorough oxidation of organic compounds, achieving lower detection limits than combustion methods
• NDIR Detection: Non-dispersive infrared CO₂ measurement provides excellent specificity and linear response across the full range
• 5 ppb Detection Limit: Ten-fold improvement over combustion-based analyzers enables trace-level monitoring for high-purity water applications
• Multi-Parameter Capability: Simultaneous determination of TC, TIC, TOC, and NPOC in a single analysis sequence
• Intelligent Signal Management: Advanced 32-bit processing with automatic online settings, real-time monitoring, and self-diagnostics
• Automatic Safety Systems: Built-in leak detection and flow rate control ensure safe, reliable operation
• Compact Design: Lighter and more compact than combustion models while delivering comparable analytical flexibility

Operating Principle

The sample is mixed with an oxidizing reagent and exposed to intense UV radiation, which converts all organic carbon to CO₂. The generated CO₂ is carried by nitrogen gas to the NDIR detector for quantification. The UV-persulfate method provides more complete oxidation than UV alone while maintaining lower background levels than high-temperature combustion, resulting in superior detection limits for clean water applications.
