Retention gaps, phenylmethyl silylated, low–medium polar 5190-8264 NUCLEOSIL 1000-7 C18The 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). Phenylmethyl (low medium polar) deactivated tubing as an additional choice of surface deactivation. Improve peak shape by
