The injection of the samples is carried out using a thermal extraction device, directly connected to the GC. Crude oil samples are initially adsorbed on a suitable material and subsequently their light components are thermally extracted and driven into the GC by the carrier gas flow, while the heavy end remains adsorbed on the sample probe. Factors affecting the depth of the analysis, such as the kind of adsorbent material, temperature, and duration of sampling, were studied. The main advantage of the proposed technique is that no preliminary separation of the crude oil sample into a light and heavy fraction is needed prior to the GC analysis. In addition, the contamination of the chromatographic system by the heavy crude oil components is avoided.
