Primesep 500

by SIELC

Primesep 500 is a reverse-phase analytical column with embedded acidic ion-pairing groups.

  • Primesep 500 has an embedded carboxilic acid with a pKa of about 5.
  • Improves retention of basic compounds by cation-exchange mechanism at pH > 5.
  • Separates acids by ion-exclusion mechanism at a mobile phase pH > 5.
  • Retains basic compounds, as any RP column, at pH < 5
  • Retains neutral compounds by reverse-phase mechanism.
  • All mobile phases are LC-MS and preparative chromatography compatible.

Similar columns from other manufacturers to Primesep 500

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
