Field of application

Total organic carbon (TOC) content strongly influences the quality of ultrapure water. A high TOC concentration can cause damage of water purification systems or compromise the required water quality. The CA78 online TOC analyzer provides continuous, accurate TOC monitoring ensuring consistently high quality of the ultrapure water used in your production processes. You gain full control of your product yield and quality.

The CA78 TOC analyzer is perfectly suited to TOC monitoring of ultrapure water in the following industries:

Power & Energy
Semiconductor production
Bodycare
Disinfectant production

With the following process conditions:

Conductivity: 2 µS/cm (standard), 10 µS/cm (order option)
pH range: Neutral

Benefits

Real-time overview of water quality:
The online TOC analyzer measures continuously with a fast response time (t₉₀) of 50 seconds. This enables you to react immediately to potential water contamination and to protect your product effectively.
CA78 uses proven UV oxidation and differential conductivity measurement which is the most-established method for reliable TOC trace analysis in ultrapure water.
The analyzer's maintenance-friendly design in combination with our worldwide service network offers you complete support for the measuring point, from commissioning throughout the entire lifespan of the device.
Perfect adaption to your process needs:
Select between the high-precision 2 µS/cm conductivity version and the robust version that tolerates 10 µS/cm. Reduce your investment costs by the optional 3 channel configuration.
