Primesep PB

Primesep PB is a reverse-phase analytical column with embedded aromatic and basic ion-pairing groups.

  • Improves retention of acidic compounds by anion-exchange mechanism
  • Separates aromatic compounds by difference in pi-pi interaction
  • Retains neutral compounds by reverse-phase mechanism
  • All mobile phases are LC-MS and preparative chromatography compatible (working pH range from 2.0 to 5)

Primesep PB columns are available in all standard dimensions
Column IDs: 22 mm, 10 mm, 4.6 mm, 3.2 mm, 2.1 mm, 1 mm, 0.5 mm, 0.25 mm
Column Lengths: 250 mm, 150 mm, 100 mm, 50 mm, 25 mm, 10 mm
Particles: 10 um, 5 um
Pores: 100 A
