A host of preparation methods have been developed and improved to convert different sample compounds to an appropriate gas including H2<\/sub>, CO, CO2<\/sub>, N2<\/sub>, and SO2<\/sub>. The measured values expressed in delta notation like \u03b42<\/sup>H, \u03b413<\/sup>C, \u03b415<\/sup>N, \u03b418<\/sup>O, \u03b434<\/sup>S The delta values are defined as follows: \u03b4 (\u2030) = (Rsample<\/sub>\/ Rreference<\/sub>-1) * 1000, where R is the\u00a013<\/sup>C\/12<\/sup>C,\u00a015<\/sup>N\/14<\/sup>N or\u00a034<\/sup>S\/32<\/sup>S etc. ratio in the sample or in the international reference.\u00a0The isotope results were calculated on the basis of the known values of international standard materials.[\/vc_column_text][vc_column_text]The Elemental Analyser (Fisons NA1500 NCS)<\/strong><\/span>\u00a0is based on the complete and instantaneous oxidation of the sample by flash combustion which converts all organic and inorganic substances into combustion products. The resulting combustion gases pass through a reduction furnace and are swept into the chromatographic column by the carrier gas (helium). The gases are separated in the column and detected by the IRMS (\u03b413<\/sup>C, \u03b415<\/sup>N, \u03b434<\/sup>S). Isotopic analyses of water samples or carbonates are carried out with an automated\u00a0GASBENCH<\/span> II<\/strong>\u00a0sample preparation device attached to the IRMS. Hydrogen and oxygen isotopes of the water, carbon and oxygen isotopes of carbonate samples are measured by this method. The high temperature conversion elemental analyser\u00a0(TC\/EA)<\/strong><\/span>\u00a0coupled to the IRMS is suitable to determine the \u03b42<\/sup>H and \u03b418<\/sup>O values of solid samples and of fluid samples as well.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”388″ img_size=”full”][\/vc_column][\/vc_row][vc_row][vc_column][vc_btn title=”Back to INFRASTUCTURE subpage” style=”outline-custom” outline_custom_color=”#000000″ outline_custom_hover_background=”#dc343b” outline_custom_hover_text=”#ffffff” shape=”round” size=”sm” i_icon_fontawesome=”fas fa-arrow-left” add_icon=”true” link=”url:https%3A%2F%2Finteract.atomki.hu%2Fen%2Finteract-center%2Finfrastructure%2F|title:Infrastructure”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
