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

Print Friendly, PDF & Email

 

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
 Column temp. : 40degC
