Analysis of Anions in Water

Shim-pack IC-SA2 was developed for anion analysis with a Shimadzu Ion Chromatograph HIC-SP (suppressor type). It is capable of
analyzing fluoride ions, chloride ions, nitrite ions, bromide ions, nitrate ions, phosphate ions, sulfate ions, etc., making it possible
to be used in both tap water and environmental water analysis.

High-Resolution Determination of the Components in Water-Quality Analysis
Environmental water and mineral water usually contain
silicate. In this kind of analysis, although the water
sample contains a large amount of silicic acid, fluoride
ions can still be separated and determined with high
resolution (same mobile phase as above was used).
