A new type of capillary column for gas chromatography

A new type of capillary column for gas chromatography was proposed, A sorbe nt layer (for example, stationary liquid phase) is supported oil the intern al capillary Surface, and the internal (interstitial) volume is packed with nonporous large particles of a sorbent (particle diameter is 0.1-0.6 of th e capillary internal diameter). The external surface of the particles can a lso be coated with the sorbent layer (for example, stationary liquid phase) . The specific separation efficiency (number of separation) oil the new typ e column is by 1.6-2.3 times higher than that of the initial classical capi llary column.
