What is a TOC analyzer and why is TOC analysis crucial?
A TOC analyzer (total organic carbon analyzer) is a high-precision measuring device for determining the total organic carbon content in water. TOC analysis has established itself as the gold standard
for assessing organic pollution in a wide variety of water types – from ultrapure water in semiconductor production to wastewater in sewage treatment plants.
The organic carbon content is a key indicator of water quality, as it provides information about the concentration of organic contaminants. TOC analyzers enable these parameters to be monitored continuously and in real time, which is essential for process reliability, quality control, and regulatory compliance.
Why measure TOC instead of conventional parameters?
Compared to traditional parameters such as BOD (biochemical oxygen demand) or COD (chemical oxygen demand), TOC analysis offers decisive advantages:
- Speed: Results in minutes instead of days
- Precision: Direct measurement of organic carbon without interference
- Reproducibility: Standardized methodology with high repeatability
- Comprehensive detection: All organic compounds are detected, not just biodegradable ones
Modern TOC analyzers use various oxidation methods—from UV oxidation to high-temperature combustion—and offer different advantages depending on the application. The choice of the right TOC analyzer depends on factors such as the measurement range, sample matrix, regulatory requirements, and operating environment.
Measuring principles and technologies
The catalyst-free high-temperature combustion of the Tocadero ONE at 1,200 °C ensures the complete oxidation of even difficult-to-degrade organic compounds. Advantages:
- Complete oxidation of all organic compounds
- No catalyst poisoning or aging
- High measurement accuracy even with complex matrices
- Extended measuring ranges up to 50,000 ppm
- Low-maintenance operation even with saline water
The UV oxidation of the Tocadero EVO uses high-energy UV radiation to break down organic molecules. In combination with differential conductivity measurement, this results in precise measurement results. This method is particularly suitable for:
- Low TOC concentrations (µg/L range)
- Pure and ultrapure water applications
- Reagent-free analysis
- Continuous online measurement with results in seconds
