Primesep S

Primesep S is a normal-phase analytical column with embedded acidic ion-pairing groups

  • Most suitable for separation of common sugars and other neutral or very polar molecules
  • Retains and separates amino acids with different buffers at low concentration
  • Separates weak bases by ion-exchange mechanism
  • Separate acids by ion-exclusion mechanism
  • All mobile phases are LC-MS and preparative chromatography compatible (working pH range from 2.0 to 7.0)

Primesep S 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 µm, 5 µm, 3 µm, 2.7 µm (solid core)
Pores: 100 A
