SIELC Technologies

SIELC Technologies has developed mixed-mode Columns based on solid-core-porous-shell particles. This separation media combines the efficiency of solid-core technology with the unique selectivity of Ion-Exchange (IE), reverse phase (RP), surface chemistry and ion-exchange HILIC surface. Please read more about solid-core technology here.

Solid-Core Primesep SB is a reverse-phase analytical solid-core column with strong embedded basic ion-pairing groups. It contains a C18 carbon chain and basic quaternary amine groups.

It provides the following capabilities:

– Enhances retention of acidic compounds through anion-exchange mechanism.
– Separates hydrophobic basic molecules using a combination of ion-exclusion and reverse-phase mechanism.
– Retains neutral compounds by reverse-phase mechanism.
– Offers mobile phases suitable for LC-MS and preparative chromatography, as well as low UV detection (working pH range from 1.5 to 5).

Solid-Core Primesep SB is a reverse-phase analytical column with strong embedded basic ion-pairing groups.
