SGE GC Capillary Columns

Since the early 1970's, SGE has been recognized as a pioneer in the development of capillary columns for gas chromatography with an extensive team of polymer chemists, glass technicians and chromatography specialists working on new techniques. SGE was the first to develop and offer several new classes of stationary phases including the sol-gel range of columns.

Column Selection

Stationary Phase

  • Choose the least polar phase that will perform the separation you require.
  • Choose SOLGEL-WAX™ to separate compounds such as alcohols, ketones, aldehydes and esters.
  • The 5% phenyl columns (BPX5) can be used in 90% of all separations.

Effect of stationary phase. BTEX analysis on two phases of columns. 30m x 0.25mm ID x 0.25um film (SGE).

Internal Diameter

  • The smaller the diameter, the faster the analysis.
  • 0.25mm ID columns are suitable for most applications, especially GC-MS.

Effect of internal diameter. Polynuclear Aromatic Hydrocarbon (PAH) analysis (SGE).

Film Thickness

  • 0.25um films are standard.
  • Use >= 0.5um films for volatile compounds.
  • Thicker film columns will result in longer run times but better resolution.

Effect of film thickness (SGE).


  • Doubling the column length improves resolution by 40%.
  • 30 meter columns are standard.
  • Choose short columns for active compounds.

Effect of length (SGE).
