Zation), the place D may be the optical density in the maximum absorption band of corresponding compounds [33,38]. The evaluation in the group and individual hydrocarbon composition of saturated and aromatic fractions was carried out by GC/MS on a Thermo Fisher Scientific instrument with an ISQ LT Single Quadrupole mass selective detector primarily based on a Chromatec-Crystal 5000 chromatograph with Xcalibur software program. The energy of ionizing electrons was 70 eV. We applied a CR-5ms quartz capillary column 30 m prolonged and 0.25 mm in inner diameter with a deposited methylsiloxane phase (0.25 ). The flow fee of carrier gas (helium) was one mL/min. The YC-001 Antagonist temperature of the injector was -310 C along with the thermostat temperatureProcesses 2021, 9,4 ofBMS-8 Inhibitor program was adjusted as follows: temperature rise from 100 to 150 C at a rate of twelve C/min, from 150 to 300 C at a price of three C/min followed by an isotherm till the finish of your examination. The total analysis time of a sample was 70 min. All samples have been diluted in carbon tetrachloride at a concentration of 10-3 g/ in advance of being introduced into the gadget. Chromatograms have been recorded, according to the complete ionic current (TIC), followed by reconstruction of your molecular fat distribution of different sorts of compounds by characteristic ions: n-alkanes and acyclic isoprenoids (m/z 57 113), alkyltrimethylbenzenes (m/z 133 134), triterpanes ( m/z 191), steranes (m/z 217 259) and monoaromatic steroids (m/z 253) in saturated fractions; naphthalenes (m/z 128 142 156 170), phenanthrenes (m/z 178 192 206), benzothiophenes (m/z 147 161 175) and dibenzothiophenes (m/z 184 198 212) in aromatic fractions [399]. The processing of mass spectral information was carried out, employing the Xcalibur plan. Compounds had been identified, making use of the NIST 02 electronic mass spectra library and literature information. The relative content material of numerous groups of compounds was estimated by calculating and comparing the places on the peaks corresponding to person compounds on mass chromatograms (Si) relative to your total area of all peaks (Si) with the identified compounds. 3. Success and Discussion Characterization of rock samples from the pyrolytic Rock val strategy. Based on the success obtained in the pyrolytic Rock val strategy, the organic carbon content (Corg )while in the carbonate rock sample of Zelenogorskaya area was 3.03 , even though in carbonatesiliceous rocks of Berezovskaya region, it had been 7.44 (Table 1). Based on the classification of Tisso and Welte (1984), the rocks are divided into two varieties: very good (Corg 3 ) and excellent productive deposits. The major difference on the given rock samples is during the pyrolysis parameters. The S1 worth, which shows the share in the first genetic potential of OM transformed to the free hydrocarbons, is equal to 9.91 and two.29 mg HC/gr of rock.Table 1.
