Effective procedures have been developed to pack fused silica (capillary) columns with 5-..mu..m particles of silica adsorbent and other polar materials (diol-, cyano-, and amino-bonded phases). Microcolumns exhibiting overall efficiencies between 70,000 and 90,000 theoretical plates were prepared. The reduced plate heights, separations impedance, and sample capacity of such columns were further evaluated.
