Separation of Na + and NH 4 + (1) (Non-suppressor Method)

With about twice the theoretical plate number and about 1.3 times the Na⁺/NH₄⁺ resolution, YS-50 can be applied to NH₄⁺ analysis at a high concentration of Na⁺ (Na⁺:NH₄⁺=5,000:1 is possible).

Sample : 10micro-L
Na⁺ 50ppm
NH₄⁺ 0.01ppm

 Column : Shodex IC YS-50 (4.6mmID*125mm)
 Eluent : 4mM Methanesulfonic acid aq.
 Flow rate : 1.0mL/min
 Detector : Non-suppressed conductivity
