Profile

Capillaryliquid chromatography/Miniaturization of separation columns has been investigated in liquid chromatography (LC) for more than a quarter century. Advantages of capillary columns in LC are attributed to narrow column diameter and low eluent flow rate. Development of capillary columns with much higher efficiency than conventional LC columns will shift users from conventional to capillary LC, as seen in the development of capillary GC. Columns with highercolumn efficiency must have higher permeability in comparison with common densely packed columns. Open tubular capillary columns and monolithic columns are expected to achieve higher column efficiency because of their higher permeability. At this moment, monolithic silica columns can be one of candidates for such a highly permeable separation system. Capillary LC will save energy and wastes. It will also improve column efficiency of LC and facilitate hyphenation with MS, leading to acquirement of more accurate analytical results in the very near future./Ion chromatography/1.
