9210p Online TOC Analyzer



The Model 9210 Online TOC Analyzer has been discontinued and is no longer in production. The 9210 has been replaced with the Model 9220 Online TOC Analyzer, which will be available later in 2023. The Model 9220 offers enhanced capabilities over its predecessor in operation and functionality. 

  • Overview

    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.

    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
