Primesep C

Primesep C is a reverse-phase analytical column with embedded complex-forming groups.

  • Improves retention of positively charged compounds by forming a host-guest complex.
  • Retains neutral compounds by reverse-phase mechanism.
  • All mobile phases are LC-MS and preparative chromatography compatible.

Primesep C columns are available in all standard dimensions
