Print

Analysis of mineral water was performed using IC YS-50 (a column for cation chromatography). It turns out that many divalent cations is contained in mineral water.


Sample : Mineral water, 10μL
1. Na+
2. NH4+
3. K+
4. Mg2+
5. Ca2+


Column       : Shodex IC YS-50 (4.6mmI.D. x 125mm) 
Eluent       : 4mM Methanesulfonic acid aq.
