Primesep Complex

Primesep Complex SiELC

Primesep C is a reverse-phase analytical column with embedded complex-forming groups. It improves retention of positively charged compounds by forming a host-guest complex with amino compounds and metal ions. With a reverse stationary phase as a basis for primary interaction, the column offers a typical RP retention profile for neutral compounds. In addition, embedded hosting groups interact with amines and other ions, resulting in unique selectivity. Amines with equal hydrophobicity retain on Primesep C in the following order: tertiary<secondary<primary. Alkali metals are retained in order K+<Na+<Li+, which is a reverse order compared to the classical ion-exchange.
