GC Micropacked Columns
Analytical Column for Gas Chromatography Applications
Conventional packed columns consist of tubes with inner diameters of 2-4 mm and lengths of 0.5-6 m, and which are packed with supports comprised of stationary phases coated with liquid phases. With changes in analytical trends, many varieties of packed columns have been replaced with capillary columns. However, because gaseous samples occupy large volumes and easily diffuse at room temperature, there are still a large number of unfavorable factors preventing a complete switch to capillary columns, with the result that many analyses of these kinds of samples still rely on packed columns. The MICROPACKED ST column was developed to be used in the same manner as capillary columns, as well as provide increased sample loading capacities.
