Abstract
The chromatographic performance of 50 mu m internal diameter (i.d.) fu sed silica columns coated with up to 2 mu m films of immobilized SE-54 (methyl phenyl (5%) silicone) is evaluated under gas chromatographic conditions. The influence of pressure drop on the plate height is disc ussed. In comparison to thick film 250-530 mu m i.d. columns, much hig her efficiencies and faster analyses are obtained. Practical examples, performed on a standard GC instrument, illustrate the features of thi ck film 50 mu m i.d. columns.
