Packed GC Columns

Packed GC columns remain a valuable option in gas chromatography for high-capacity applications and for analytes that are difficult to separate using other techniques. These columns, traditionally constructed as short, wide tubes typically made from stainless steel or glass and packed with a solid support coated with a stationary phase, have been used since the earliest days of GC. Although they produce broader peaks and lower separation efficiency than capillary columns, they continue to support essential analyses in the hydrocarbon processing industry and in official standard methods for gas analysis. 

Modern packing technologies provide consistent, reproducible performance, while options such as UltiMetal deactivated stainless steel tubing help deliver sharper peaks with reduced tailing. With a wide selection of tubing materials, stationary phases, packings, and support materials – and the option to request custom packed GC columns – packed columns offer flexible, reliable solutions for specialised gas chromatography workflows.
