摘要：

Glass and stainless-steel preparative sorbent bed injection columns are described, which can be packed with spherical particles of silica gel and silica-based reversed-phase material, particle size 15 μm, by simple gravity sedimentation. Columns of I.D. 42-44 mm and 250 mm long give symmetrical peaks with loads of 1-2 g; by using sorbent bed injection their lifetime is greatly increased and the use of a compression piston is not needed. © 1990.
