Monitoring Organic Contaminants in Water and Wastewater Streams? Learn from our TOC guru! 

What is TOC? How is it Measured?

Total organic carbon (TOC) measurement is a well-established technique that provides valuable information about water quality for process control and regulatory compliance. Though high-temperature combustion TOC has been shown to be very effective for the analysis of samples that are of high molecular weight or contain substantial amounts of salt or difficult-to oxidize organics (e.g, humic acid), these types of samples are problematic for combustion TOC analyzers.

Need to monitor organic contaminants in water and wastewater streams? Our 9210p Online TOC Analyzer was developed from 45 years of experience, so it addresses important issues like performance, reliability, simplicity, and cost-effectiveness. 

Reliable Data for Regulatory Compliance and Process Control

The 9210p is fully compliant with USEPA Method 415.3 and SM 5310C. It combines the robust heated persulfate oxidation method with a patented, solid-state infrared detection technology for unparalleled accuracy and precision across a range of 50 ppb to 250 ppm.

Engineered for operation in process environments, the 9210p requires no external gases, minimal preventative maintenance, and uses standard reagents. Calibration is typically stable for 12 months.

9210p TOC Features:

  • Flexible - Ideal for drinking water, municipal wastewater, surface water, ground water, and other industrial water streams
  • Reliable - Compliant with USEPA Method 415.3 and SM 5310C
  • Economical - Uses standard reagents, does not require external gases or expensive service contracts
  • Simple – A large, touchscreen display, paired with an easy-to-use interface, simplifies set-up and access to data, trending, and diagnostic screens
