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 NH₄⁺ 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)
