Ultra Pure Water

What is Ultra Pure Water?

Ultra pure water, as the name suggests, is water purified to the highest standards making it completely free of contaminants. This level of purification is required for advanced analytical techniques, such as HPLC, and is commonly used for semi-conductor manufacturing. To produce ultra-pure water a combination of different purification techniques is required to remove different contaminants.

This can include ion-exchange resin, synthetic activated carbon, UV photo-oxidation lamps, micro filtration membranes, ultra filtration membranes. Some systems operate directly from tap water and others from pure water. Due to the high level of purification ultra pure water has low levels of anionic contamination, resulting in ultra pure water having a resistance of up to 18.2 mOhm-cm. When selecting an ultra pure water purification system consider; the available feed water, necessary volumes, and required water quality monitoring.
