Diesel oil analysis column offers a new dimension in 2D chromatography

May 15 2019 Read 83 Times

JSB will be exhibiting on stand 39 at PEFTEC and will focus on the use of the Agilent J&W DB-Heavywax column as the second dimension in comprehensive 2D chromatography (GCxGC) for the analysis of diesel oil.

To provide enhanced separation power and superior peak capacity, GC×GC combines two analytical columns, called dimensions, within one analytical method. Thanks to these unique features, GC×GC has become the method of choice for the detailed characterisation of highly complex samples that cannot be approached with traditional GC. This is the case for many petrochemical products, which are very challenging due to the huge number of compounds covering a wide range of volatilities and chemistries.

With this column, analysis takes less time with an extended operational range for higher boiling compounds. With good thermal stability after repeating the heating cycles up to 280 °C performance did not show significant signs of deterioration, even for the critical test provided by the fast, sharp two-dimensional peaks.
