Thermo Scientific Orion 7070iX Total Residual Oxidant (TRO) analyser

Friday, 24 May, 2019 | Supplied by: Thermo Fisher Scientific



The Thermo Scientific Orion 7070iX Total Residual Oxidant (TRO) analyser is designed to measure low ppb chlorine concentrations in treated wastewater in line with stringent regulatory requirements.

Providing high sensitivity for low-level chlorine measurements down to 1 ppb with 1 ppb resolution, the system is designed to give users the confidence that chlorine concentrations in water discharged into natural water sources do not exceed the safety threshold or pose a threat to marine life. The analyser also enables full range measurements up to 15 ppm.

Compared to the conventional DPD (N,N-Diethyl-1,4-Phenylenediamine Sulfate) colorimetric method, the iodometric electrode technology does not suffer from turbidity or colour interferences, which can have a negative impact on result accuracy and precision.

The analyser is also capable of operating autonomously for long periods of time with minimal instrument drift (<5% for >180 days without calibration) eliminating the need for routine maintenance. At the same time, the system’s self-cleaning capability prevents chemical and biological fouling of the measurement cell and sensor, minimising downtime and facilitating continuous testing.
