Deionized Water for Ion Chromatography

Specially deionized water suitable for IC is provided in 1 L bottles for convenient use. This water typically contains less than 10 parts per trillion (ppt) of individual metals. Although common anions are specified to be less than 1 part per billion (ppb) each, this water is not recommended for trace-level analysis without further purification. Because bottles in storage or use will equilibrate with carbonate from the air, the shelf life of an unopened bottle is specified to be three years.

This specially deionized IC water has a known purity level to reduce the occurrence of system performance problems associated with poor quality water. Bottles should be changed monthly to reduce potential for contamination.

A bottle cap adapter is available that permits use of the IC system's standard GL45 bottle cap with the 38 mm thread of the purified IC water's bottle. This makes bottle exchange simple and quick, and permits a complete seal of the bottle.
