miniTOC² Total Organic Carbon Analyzer
Brand: MembraPure
The MiniTOC² Analyzer is a next-generation Total Organic Carbon (TOC) analyzer designed for continuous online and offline monitoring of pure and ultrapure water. It combines advanced UV oxidation technology with conductivity detection for fast, accurate, and reliable TOC measurements. Optimized for efficiency and sustainability, it minimizes water consumption and maintenance costs while delivering high precision and compliance with international standards (USP <643>, EP 2.2.44, DIN EN 1484).
Features
- Optimized Sample Volume: Approx. 7mL/min, reducing water consumption by 50% compared to previous models.
- Enhanced UV Oxidation: Direct surface geometry improves oxidation performance and measurement accuracy.
- Long-Life UV Lamp: Up to 12 months lifespan, reducing maintenance and waste.
Continuous Measurement: Every 2 seconds for real-time monitoring. - Low Detection Limit: 0.5 ppb with an extended range up to 1500 ppb.
- Multi-Inlet Capability: Up to 3 sample loops (Pro version).
- Remote Service & Cloud Connectivity: Enables online diagnostics and easy maintenance.
- IP54 Protection: Dust and water jet protection for durability.
- User-Friendly Software: Detailed system status, data export options, and optional 21 CFR Part 11 compliance for pharma.
- Upgradeable Options: Autosampler, additional pump, heat exchanger, pressure regulator, and validation documents (IQ/OQ/PQ).
