Retention gaps, CW (carbowax, polyethylene glycol), polar ICP-33N-5 more accurate reloading and excellentThe 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). Carbowax (CW, polyethyleneglycol, polar) deactivated is suitable for direct aqueous injection. Improve peak shape by
