Sea Water (2) (YS-50)
Sea water diluted 100 times was analyzed using IC 
YS-50 (a column for cation chromatography) 
by non-supprresor method. YS-50 are suitable for analysis of NH
4+ at a high concentration of Na
+, 
such as sea water.
Please refer to 
Monovalent and Divalent Cation Standards (6) (Comparison of YS-50 and YK-421)
