C18-W TLC Plates

Octadecyl-Modified Silica Layers

Our C18-W plates feature a partial octadecyl (C18) modification of the silica with a carbon content of 14%. They can be used in Normal Phase or Reversed-Phase separation modes with eluents from anhydrous solvents to mixtures with high concentrations of water.

Features:

  • Order of polarity: Silica > DIOL > NH2 > CN > C2 > C18-50 > C18-W > C18-100
  • Wettable with water, can be used in Normal or Reversed Phase modes
