miniTOC Analyzer

The miniTOC Analyzer is a compact, high-precision Total Organic Carbon (TOC) analyzer designed by membraPure GmbH for continuous or offline monitoring of TOC levels in ultrapure and pharmaceutical-grade water systems. Compliant with pharmacopoeia standards (USP <643>, EP 2.2.44), the miniTOC is optimized for online measurement, ensuring consistent water quality for critical laboratory and industrial applications. Built on the UV-persulfate oxidation method with conductivity detection, the miniTOC is capable of detecting low ppb-level TOC concentrations, making it ideal for cleanrooms, pharmaceutical manufacturing, and semiconductor water systems. It features a low-maintenance design, automatic calibration, and 21 CFR Part 11–ready software, making it compliant and user-friendly.
