SIELC Primesep

SIELC Technologies introduces Primesep® HPLC columns, specifically designed for mixed-mode separations and capable of separating a tremendous range of compounds by different separation modes based only upon mobile phase selection.

Choose the correct column by their functional group acidity to match the pKa value of your basic compounds.

Columns with negatively charged functional groups due to the embedded anionic ion-pairing reagent.

Primesep A: Strongest acidic phase
Primesep 100: Strong acidic phase
Primesep 200: Medium acidic phase

Columns with positively charged functional groups.

Primesep B: Strong basic column for use with TFA, phosphoric or perchloric acid solutions in a mobile phase.

Primesep B2: Weak basic column for ammonium acetate buffered solution.

Column with unique unparallel selectivity.

Primesep C: Combined reverse-phase and complex formation properties for interaction with amines, sulfonium, phosphonium and metal ions.

Three interactions within one column: reverse phase, pi-pi, strong cation exchange
Primesep P: Choose for separation of structural isomers of aromatic compounds.
