Tap Water and Red Wine

Tap water and red wine were analyzed using IC Y-521.
Tap water and red wine contain Zn2+ as well as Mg2+ and Ca2+. Since the trivalent cations such as Fe3+ and Al3+ are changed into complex ions and elute first, they never remain in the columns nor damage them.


Sample :
Tap water(Water), 100micro-L
1. Zn2+
