Comprehensive multidimensional separations for the analysis of petroleum.

Petroleum analysis presents many unique challenges as a result of the overwhelming number of compounds present in petroleum samples. Consequently the use of multidimensional separation techniques will almost invariably be required in order to overcome these challenges. Within this paper we review recent developments in the application of comprehensive multidimensional techniques for petroleum analysis focusing on more recent applications. Basic instrumentation for various comprehensive multidimensional techniques is outlined along with an overview of a broad range of applications in both group-type and target molecule analyses for petroleum and biofuel analysis. In addition, strategies for data interpretation and chemometric analysis of multidimensional data are also reviewed.
