Pyrolysis-GC×GC-QTOF for the Improved Characterisation of Crude Oil

May 21 2018

JSB have released a new application note describing how to overcome the challenges of detailed composition characterisation in crude oil.

Pyrolysis coupled to comprehensive two-dimensional gas chromatography-mass spectrometry (py-GC×GC-MS) is a very powerful technique for the characterisation of complex, heavy matrices such as crude oils. In the application note the Pyrolysis-GC×GC-OTOF method was applied to 3 samples from different origins and with differing density and sulphur content.

The results substantiated that two-dimensional resolution provides enhanced separation of the pyrolysis products, leading to improved classification for groups and individual analytes. Additionally, the 2D pyrograms make sample comparison easier and more informative. In spite of the enhanced separation power offered by GC×GC, complexity is such that complete resolution is often not possible. The use of High Resolution Mass Spectrometry (HRMS) can deliver extra selectivity and identification power, especially for compounds with heteroatoms (e.g. N, S, O).
