The Hach BioTector B3500ul is a high-precision online TOC analyzer specifically designed for ultra-low range organic carbon monitoring. It is the ideal solution for critical water applications, such as pharmaceutical UPW (Ultra-Pure Water), semiconductor manufacturing, and power plant cycle chemistry, where detecting trace levels of contamination is vital for process integrity.
The B3500ul (Part No. B5EBAA152EAF2) utilizes Hach’s patented Two-Stage Advanced Oxidation (TSAO) technology to provide highly sensitive measurements in the parts-per-billion (ppb) range. Unlike standard analyzers, the B3500ul is optimized for clean water applications, featuring a specialized 0 – 5,000 µg/L C measuring range. This ensures that even the slightest organic breakthroughs are detected before they can impact product quality or damage expensive equipment like turbines or ion exchange resins. The system is designed for maximum reliability with a 99.86% uptime record and requires minimal maintenance. Housed in a compact, space-saving enclosure, it provides direct measurement of Total Organic Carbon (TOC) and can be configured to monitor Total Inorganic Carbon (TIC) and Total Carbon (TC) to ensure comprehensive water quality oversight.
Advantages
- Ultra-Low Detection: Engineered to provide accurate and repeatable measurements in the low ppb range, essential for ultra-pure water systems.
- Maximum Uptime: TSAO technology ensures 99.86% reliability, providing continuous monitoring with minimal risk of sensor fouling or failure.
- Low Operational Costs: Features industry-leading six-month service intervals, significantly reducing the need for reagents and technician intervention.
- Fast Response Time: Delivers critical data quickly, allowing for immediate corrective action in the event of an organic contamination event.
- Compact Footprint: The small, wall-mounted design allows for easy integration into existing water treatment skids and laboratory settings.
- Superior Oxidation: Patented hydroxyl radical oxidation ensures complete recovery of all organic species, providing more accurate results than UV-only methods.
