Special Features

  • A retention gap must be inert without any noticeable retention
  • Me-Sil retention gap only for use with n-hexane and diethyl ether
  • Phe-Sil retention gap for all solvents except methanol and water
  • CW retention gap for all solvents and especially for methanol and water

Description

The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column. Choice of the retention gap depends on the solvent used: the flooded zone after injection should be between 20–30 cm/µL.
