I am trying to separate nucleotides with a columm called NUCLEOSIL 100-5 SA
from machery-nagel ( it's a strong anion-exchange columm ).
The solvent is KH2PO4 50 mM-1000 mM pH 5,6 in 45 mns.

The problem is that everything is eluted in the 5 first minutes without any
I try to separate GMP, GDP, GTP, GP4G, and ADP.

I would appreciate some help.
Thanks for your time.
