Problems in finding the right GC-Column for your application?

With over 50 years experience, GC capillary columns truly are SGE’s strength.

SGE is the only independent manufacturer of GC capillary columns that has the skill and technology to control all critical processes from producing the fused silica capillary tubing, through the phase synthesis, to the validation of the performance of each column.

SGE offers a comprehensive range of GC capillary columns for almost any chromatographic application providing the best possible combination of Performance, Robustness, Reproducibility, Low Bleed and Inertness.

With these columns a big variety of applications in different areas of analysis can be performed:

• Environmental: The widespread use of GC-MS for Environmental analyses requires both low bleed and inertness. The broad range of compounds of interest means that medium polarity phases become more useful, which is given by the BP-Series of SGE (e.g. PAH, PCD and PCB)

• Food, Flavors: GC analysis in the Food, Flavors and Fragrances area covers a diverse range of compounds that vary in both polarity and boiling point. As a consequence a range of different columns or even column coupling are often required (e.g. Eucalyptus oil, wine Omega-3 Fatty acids, FAME)

• Fuels and Petrochemical: For the GC analysis, one of the main considerations is the thermal stability of the column, both physical and chemical (e.g. Refinery Lubrication Oil, Unleaded Gasoline)

• For general chemical analysis, a good rule of thumb is to use the lowest polarity column that provides sufficient separation. Particular classes of compounds, such as alcohols, amines, or organic acids, may require thicker film phases, or specific phases

• Pharmaceuticals: The GC analysis of pharmaceuticals covers a wide range of compounds that can vary greatly in their molecular weight, reactivity, and pH. Therefore a variety of different specific columns is available (e.g. USP methods, tricyclic Antidepressants, Dioxane Impurities)

• Forensic and Toxicology: These methods are often very challenging due to the analysis of very active compounds as well as coming from samples that are detrimental to GC systems. These compounds are generally basic in nature that makes inertness of the system components critical to successful determinations (Acidic/Neutral Drugs, Underivatized Barbiturates)
