“…The individual groups of hydrocarbons were distinguished in SIM mode on the basis of the increased content of the following diagnostic fragments: m / z = 71, 85 for isoalkanes, m / z = 68, 69 for alkylcyclopentanes and m / z = 82, 83 for alkylcyclohexanes [ 21 , 22 ]. n -Alkanes were identified by comparing their retention times with those of standards ( n -tritriacontane) and waxes of known hydrocarbon distribution (beeswax, Paraffin 62400, Kremer Pigmente GmbH & Co. KG, Aichstetten, Germany).…”

When treating historical beeswax seals, it seems a natural choice to use materials as similar to the original as possible. The properties of analogous recent materials, however, differ from those of the aged ones, not to mention the fact that the exact composition of the particular sealing wax is usually uncertain. In order to obtain the material of desired properties, recent beeswax is often combined with various additives, including petroleum waxes, or even replaced by mixtures based solely on these products. Within this study, the relevant properties of Permulgin 3274, a ceresin-type wax, were compared with the characteristics of recent and historical beeswaxes. The aim was to evaluate its advantages and limitations, in terms of its possible use for the conservation of beeswax seals. The properties studied were comprised of the chemical composition, thermal properties, mechanical properties, possibilities of colour adjustment and ageing properties. Permulgin 3274′s workability was evaluated by conservators from the National Archives in Prague. The results indicate that, from the technological point of view, Permulgin 3274 could be considered a welcome alternative to the use of traditional conservation mixtures.

“…It is a two-step process that involves separating hydrocarbons using gas chromatography and then identifying them using mass spectrometry. [31][32][33][34][35] The most important method used to detect hydrocarbon pollution is spectroscopic analysis, because when hydrocarbons are present in soil or water, they give distinctive spectral fingerprint. [36][37][38][39][40] Spectral imaging, which constitutes hyperspectral remote sensing techniques (HRS), can be used to detect the spectral absorption and reflection features of contaminated samples due to the chemical and physical properties of the materials.…”

Field companies are subject to many standards to preserve the environment. Oil companies are considered among the companies that cause the most environmental pollution for two reasons: the first is the extraction of large quantities of crude oil, and the second is their violation of the controls imposed on them. In this research the investigations on the nearby and around a Rumaila oil station area were abducted scientifically through a real tested sample. In this research, investigations in an area near and around the Rumaila Oil Station were conducted scientifically through real laboratory samples. An analysis was made to determine the total petroleum hydrocarbons (TPH), where 22 samples were collected, as well as 5 laboratory samples of soil from an unpolluted area, and crude oil was added to it in known proportions to determine the spectral signature. The ASD Field spec 3 device was used to record the spectral signatures of each sample. Areas sensitive to hydrocarbons 17050 and 1350 appeared. The results show a variation in the concentrations of hydrocarbon in the samples from (2 ppm) at the minimum and reach (197 ppm) at other locations around the station.
