Fluorinated silicone-modified silica gel column

Wakopak® Fluofix®-II 120E

00485_img01.jpg

Fluofix® is a column packed with a carrier of high-purity spherical silica gel chemically modified with fluorinated silicone. As with hydrocarbon-based chemically modified packing agents (C18, C8, etc.), separation is basically performed in the reversed-phase distribution mode. However, the separation behavior is specific to each compound due to the strong water- and oil-repellent and rigid molecular structure of fluorinated silicon.

Features

  • Easier application of basic compounds to LC/MS analysis
  • Specific ability to recognize halogen atoms
  • Shows excellent structural recognition with rigid structure
