摘要：

Packed microcapillary columns for high-performance LC are prepared by drawing alumina or silica particles inside the thick-walled glass tubing, and a subsequent in situ bonding of various silanes to their surfaces. The columns with different selectivities were prepared, including a polar phase, a re-versed-phase column, and an ion-exchanger packing. Chromatographic results are presented with standard solutes. Microcolumns with different selectivities and very high efficiencies are now available. © 1979, American Chemical Society. All rights reserved.
