High-purity and Ultra-pure Water

Extreme clean room conditions demand extreme analysis. The reliable detection and removal of the slightest salt concentrations or the minutest particles prevents costly wastage.

Pharmaceutical companies and manufacturers of semiconductor plates and cosmetics demand maximum purity of the materials they use. Even the water has to meet extremely high quality criteria. Only ultra-pure water that contains virtually no ions is used. The electrical conductivity of the ultra-pure water is even less than that of distilled water. 

The key parameters in high-purity water are:

• TOC 
• Conductivity 
• Ozone for sanitisation with ozone 
• Particle numbers and sizes
• Dissolved gases (e.g. oxygen and nitrogen in the semiconductor industry)
• pH

Not only does the production water have to be extra pure, the production environment itself also needs to be as free from particles as possible. This is why airborne particles are regularly measured in clean rooms and even continuously monitored in grade A areas.
