flexiTOC The next generation TOC analyzer for Tap Water to Ultra Pure Water The flexiTOC is a high-sensitivity Total Organic Carbon (TOC) analyzer designed for tap water to ultra pure water applications. The analytical method is based on UV oxidation of organic carbon compounds in aqueous samples to carbon dioxide (CO₂). The generated CO₂ is quantified using a highly sensitive NDIR detector, ensuring excellent detection limits and measurement stability. The system supports reagent-free operation for TOC levels below 2000 ppb and operation with reagent for higher TOC concentrations and less oxidative substances, depending on the application. Technical Speciifications & Requirements method & detection UV oxidation with CO₂ detection (NDIR) tap to ultra pure water sample volume 5 – 30 mL reagent or dilution water is added automatically Sample interval 5 -10 min, user defined interruptions up to 24h measurement range detection accuracy < 500 ppb ± 5 ppb, > 500 ppb ± 1 % within non diluting mode 1 for sample, 1 for dilution water, 1 for reagent | 1 for sample, 3 for SST related norms ambient parameters relative humidity: 10 to 95 %, temperature: 10 to 45 °C interface ports analog (0 - 20 mA), according to Namur NE43 N2, O2, compressed air, gas pressure: 1 - 4 bar, consumption: approx. 12 L/h inlet pressure & temperature < 0.5 bar (> 0.5 bar pressure reducer is needed)

Options & Features Multiline Mode The flexiTOC pro is providing 4 different inlets. The additional software upgrade allows the user to measure up to 3 loops sequentially, and configure the duration of each interval measurement separately. Sample mode A sample mode configuration is available, and used to measure separate samples offline. This sequence can be customized by the user. Enhanced hardware performance Optimized UV reactor geometry and harmonized gas flow maximize oxidation efficiency, supported by continuous monitoring with automatic zero-flow alarm.
