Foreword

GB/T 18340 "organic geochemistry in geological samples analysis methods," There are six sections. --- Part 1. Light Crude Gas Chromatography; --- Part 2. Determination of Organic Matter stable carbon isotope isotope mass spectrometry; --- Part 3. Determination of heavy petroleum fractions Mass Spectrometry saturated aliphatic hydrocarbon component; --- Part 4. heavy petroleum distillate aromatic aliphatic component mass spectrometry; --- Part 5. rock and extract crude oil saturated hydrocarbon analysis by gas chromatography; --- Part 6. Gasoline Hydrocarbon Mass Spectrometry. This section GB/T 18340 Part 2. This Part replaces GB/T 18340.2-2001 "Organic geochemical measurements of geological samples stable carbon isotope composition of organic matter analytical Law, "compared with the GB/T 18340.2-2001, the main changes are as follows. Name --- The section from "Organic geochemical measurements of geological samples stable carbon isotope composition of organic matter analysis method" to "geological samples Geochemical analysis of organic products - Part 2. Determination of Organic Matter stable carbon isotope isotope mass spectrometry. " --- Increased elemental carbon isotope analysis of online content. --- Original standard has been adjusted the structure and content, and make appropriate editorial changes. --- This section with precision repeatability r and reproducibility R relative standard instead of the original double differential D. Appendix A of this section is informative appendix. The standard proposed by the People's Republic of China Ministry of Land Resources.
