Retention gaps, methyl silylated, non-polar Total Hardness test C₁₈ ec modified silica gel

C₁₈ ec modified silica gel is used for the purification of very hydrophilic compounds that are irreversibly retained or react with unmodified silica or used for highly hydrophobic compounds which do not show retention

Retention gaps, methyl silylated, non-polar Total Hardness test C₁₈ ec modified silica gelThe retention gap technique in combination with on column injection allows concentration of a large sample volume in the capillary column. Retention gaps consist of uncoated (no stationary phase), deactivated fused silica capillary tubing. A retention gap must be inert without any noticeable retention (analytes are not retained). Methyl deactivated surface eliminates the unwanted interaction. Improve peak shape by focusing and concentration of the
