9210p Online TOC Analyzer

Achieve reliable, economical, and real-time analysis of natural organic matter (NOM) levels in influent and effluent streams with the 9210p Online TOC Analyzer.


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. This instrument provides fast, accurate results allowing you to rapidly adjust the treatment process and more precisely control coagulation, flocculation, and formation of disinfection by-products, helping your facility stay in compliance and reduce costs.

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.
