Extract basic analytes with a positive charge from aqueous samples
TELOS SCX-2 (propylsulfonic acid) allows elution with an aqueous solvent, providing a cleaner final extract than SCX—ideal for isolating and purifying basic compounds following organic synthesis. SCX-2 columns have average pore diameter of 70 Å with 0.3 meq/g exchange capacity. All columns are made of polypropylene and come with Luer-slip outlet. Ionizable basic analytes with pK range 8 to 12.
