Puritas 120Å C-8

Overview

PURITASTM C8 phases are bonded with octyl groups and are fully end capped. They are recommended for compounds which are too strongly retained on C18 phases. PURITASTM C8 phases are available in particle sizes of 5, 10 and 15 microns for both analytical as well as preparative applications.

Key Features

  • Recommended for highly hydrophobic samples
  • Most versatile reversed phase
  • Available in different porosities
