Total Organic Carbon Analysis by Wet Chemical UV Digestion (TOC-UV)​

TOC analysis with wet-chemical UV digestion is a frequent method for testing low TOC levels in ultra-pure water, but also in challenging matrices such as highly acidic or alkaline solutions. We offer robust laboratory analyzers as well as online systems for continuous process monitoring. Discover the multi N/C 4300 UV, our trace detector for laboratory applications, and CA79, the online TOC analyzer for pharmaceutical process applications. Both work in compliance with the strict FDA 21 CFR Part 11 and other guidelines for the pharmaceutical industry.

multi N/C 4300 UV: laboratory TOC analyzers suitable for persulfate-free sample digestion
Discover our precision trace detector, the ideal analyzer for trace level TOC in pharmaceutical ultrapure water and aggressive matrices. Flow injection technology and a high-performance UV reactor make these devices perfect for ultra-trace TOC analysis in laboratory applications.  Thanks to the high-performance UV reactor with two high-energy UV wavelengths, oxidizing agents such as persulfate are not needed in the trace range. This saves both time and chemicals, as well as helping achieve a higher level of sustainability and occupational safety.

CA79: compliant TOC analysis in process monitoring 
For continuous process control, the Endress+Hauser CA79 complements laboratory analysis with real-time TOC monitoring directly in your production environment. This low-range TOC analyzer works also without reagents, applying a high-power dual wavelength UV reactor combined with differential conductivity measurement. With its fast response time it enables you to react immediately and protect your processes effectively.  

Discover the right UV-based TOC solution for your workflow.
