Support coated open tubular (SCOT) columns have an inner wall of the capillary that is lined with a thin layer of support material, such as diatomaceous earth, onto which the stationary phase has been adsorbed. Porous layer open tubular (PLOT) columns are capillary GC columns in which the stationary phase is based on an adsorbent or a porous ...

Wall Coated Open Tubular Column. A wall coated open tubular column, as the name suggests, consists of a tube in which the wall is coated with a material acting as a stationary phase. In general the tube itself is a capillary tube with a narrow inner diameter, less than 1 mm, but of very long length measuring up to tens of meters.
