| Application: | γ-DEX™ 120 column was used in ion trap GC/MS system, which was used for analysis and quantification of extracts, in an experimental study done to assess the impact of persistent organic pollutants (POPs) on human health. It was also used in GC, during the instrumentation and calibration of standards, in an experiment conducted to cycle the weathered chlordane residues in the environment. |
| Features and Benefits: | Temp. Limits: • 30 °C to 230 °C |
| General description: | Because the elution order of the members of a chiral pair frequently reverses (enantioreversal) on a γ-DEX column compared to the elution order on an α-DEX or β-DEX column, we recommend γ-DEX 120 columns as complements to α-DEX 120 and β-DEX 120 columns. γ-DEX is useful for enantiomeric differentiation of large analytes, i.e. α-BHC, carvone, carboxylic acids and methamphetamine. |
| General description: | Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column. |
