Sievers InnovOx On-Line TOC Analyzer

Real-time continuous monitoring for process control and regulatory compliance

Sievers InnovOx On-Line Total Organic Carbon (TOC) Analyzers offer continuous organics monitoring and multi-stream capabilities. The multi-stream capability allows user to run up to five samples if processes do not require continuous monitoring. The Sievers InnovOx On-Line has a dynamic operating range of 50 ppb to 50,000 ppm. Its patented Supercritical Water Oxidation technique allows for superior TOC recovery, accuracy, and instrument robustness.

InnovOx Lab Options and Accessories

  • High-temperature sampler: allow for monitoring of samples up to 85ºC. Ideal for use in steam condensate and cooling tower applications  

  • Wastewater sampler: configurable for either low to moderate or high levels of particle content without the maintenance of filtering systems 

  • Fail safe: monitors for the presence of sample flow and adequate supply of reagents/check standards to increase reliability 

  • Exterior pumps: for applications where a pressurized sample is not available
