The 9220 Total Organic Carbon Analyzer was developed from over 50 years of experience in measuring TOC for water quality monitoring, water treatment, and process water monitoring applications. With Xylem Analytics’ heated persulfate and NDIR detection technology, the 9220 provides unmatched performance, reliability, versatility, and ease of use.

The 9220 is an online TOC analyzer that employs Heated Persulfate Oxidation with NDIR detection methodology. Standard features include four-stream analysis capability, onboard carrier gas generation, autocalibration, auto validation, and intuitive software with touchscreen operation. The 9220 is self-contained in a mounting panel with a reagent tray for quick and easy installation and commissioning. Connectivity is provided through four 4-20mA outputs (one for each sample stream), Modbus, and discrete alarm outputs. The 9220’s reliability and low-maintenance design ensure reliable data collection with minimal effort.

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

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.
