By 1977, glass capillary GC columns were being manufactured and in 1982, production began on fused silica capillary GC columns . In 1983, the first special purpose fused silica capillary GC Column was introduced. Since then, an impressive list of special purpose fused silica capillary GC columns has followed.
This is the single most important characteristic in selecting a capillary column because it dictates selectivity, or the ability of the column to separate sample components. Phase selection is based on the general chemical principle that “likes dissolves like.” A non-polar column is best for the analyses of non-polar compounds. Polar
