Both GC-MS and LC-MS are widely applied in many fields. As indicated, GC-MS is limited to relatively volatile compounds. Within this restriction, GC-MS is widely applied to the identification and quantitation of compounds of environmental and pharmaceutical interest. In areas such as the characterization of oil fractions, environmental monitoring, e.g. of chlorinated pesticides like DDT and also of chlorinated dibenzodioxins, dibenzofurans and related compounds, and in a number of routine analytical procedures, e.g. in a number of clinical assays, in doping analysis in sports and for forensic purposes, GC-MS shows unsurpassed analytical possibilities, in terms of both sensitivity and identification power. 

Fractions 3-11. These fractions have a particular value as their constituents are valuable and many of them can be characterized by gas-chromatography. F3-11 contributed between 22-33 of the hearth oils and 40.5% of the total P.C.U. oil. The total yield of these fractions therefore can be used as quality index to compare different oils. This paper is a small contribution to characterization of these fractions and further work is in progress. Many new compounds have been identified and will be reported elsewhere.

Currently, the feed lump distribution is developed by routine measurement and it is unachievable for any modeling technique to accurately estimate the molecular information of oil fraction (such as PNA content, multi-ring aromatics distribution, hindered and non-hindered sulfur content) by using routine measurement only. Therefore, the resulting model is sensitive to feed stock and needs to be re-calibrated when the feed stock is changed from base case. If detail molecular information of feed stock is available, the feed lump distribution can be customized to better characterize feed stock.
