This technical article outlines the analysis of long-chain oligonucleotides utilizing a simple eluent containing acetonitrile with a relatively low level of salt and no ion-pair reagent.

The SI-36 4D does not require organic solvent to achieve the separation. Gradient conditions and phosphate ions are eluted within 15 minutes, so analysis time is short.

Monovalent and divalent cations in tap water were analyzed by IC YS-50.
