Examples of Cation Analysis

Shimpack IC-C4 is a high-performance general-purpose cation analysis column that can be used for both non-suppressor and suppressor ion chromatographs.

High Resolution of Na⁺ and NH₄⁺

High resolution of Na⁺ and NH₄⁺ has been achieved by improving the peak shape of Na⁺. The influence on the peak shape of NH₄⁺ from a high concentration of Na⁺ has been reduced, making it possible to analyze tap water of normal concentration under standard mobile phase conditions. The resolution can be further improved by using a mobile phase treated with 18-crown-6 additive.The addition of 18-crown-6 is possible only when using a non-suppressor ion chromatograph.

Analysis of Anions in Water

Shim-pack IC-SA2 was developed for anion analysis on 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.

Higher determination resolution of the components in water-quality analysis

Environmental water and mineral water usually contains 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 solution. (same mobile phase as above was used)
