The molecule is positively charged because the pH for chromatography is less than the pI (a/k/a pH(I)). In this type of chromatography, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. (wikipedia.org)

The difference between anion and cation resins is that one is positively charged (anion) and the other is negatively charged (cation), cation resins, attract positive ions with their negative charge. (deloachindustries.com)
Cation exchange5
The two types of ion chromatography are anion-exchange and cation-exchange. (wikipedia.org)

Cations4
The equilibrated stationary phase consists of an ionizable functional group where the targeted molecules of a mixture to be separated and quantified can bind while passing through the column-a cationic stationary phase is used to separate anions and an anionic stationary phase is used to separate cations.

The bound molecules then can be eluted and collected using an eluant which contains anions and cations by running a higher concentration of ions through the column or by changing the pH of the column. (wikipedia.org)
Anions and cations could now be separated efficiently by a system of suppressed conductivity detection. (wikipedia.org)
