This is an SBIR Phase II award from the 1985 solicitation. Many important problems in characterizing materials in the earth's lithosphere employ thermal analysis. The innovation offered in this project is an unique system which couples thermogravimetric analysis (TGA) with evolved gas analysis (EGA) performed with a Fourier Transform Infrared (FT-IR) spectrometer. An unique feature of the system is its ability to provide continuous monitoring of the infrared spectra of evolving liquids as well as quantitative analysis of gases. The FT-IR system combines all of the control and data reduction functions in the FT-IR's computer and thus is capable of providing an integrated, automated instrument with extensive analysis of products at a limited analysis. The Phase I program emphasized the characterization of energy resources. In collaboration with Dr. Jean Whelan of the Woods Hole Oceanographic Institute, a variety of the petroleum source rock samples were analyzed with the TG-FTIR and the results correlated with data on maturity, vitrinite reflectance, mineral composition, organic content, and organic composition obtained by standard methods. Initial results indicate that the TG-FTIR technique provides useful geochemical information related to source rock characteristics including: a) Independent maturation indicator,s Tmax of a number of organic and inorganic sediment components; b) Material balance of organic and inorganic sedimentary carbon, nitrogen, and sulfur; c) Data for classification of sedimentary organic matter into kerogen Types I, II, and III and depositional environment. Phase II will be devoted to improvements in the apparatus, in the methodology, in calibrations using a variety of standard materials and in the application technique for a variety of problems related to resource and pollution monitoring.

这是 1985 年征集的 SBIR 第二阶段奖项。 表征地球岩石圈材料的许多重要问题都采用热分析。 该项目提供的创新是一个独特的系统，它将热重分析 (TGA) 与使用傅里叶变换红外 (FT-IR) 光谱仪执行的逸出气体分析 (EGA) 结合起来。 该系统的一个独特之处在于它能够连续监测不断变化的液体的红外光谱以及对气体进行定量分析。 FT-IR 系统结合了 FT-IR 计算机中的所有控制和数据缩减功能，因此能够提供集成的自动化仪器，以有限的分析对产品进行广泛的分析。 第一阶段计划强调能源资源的特征。 与伍兹霍尔海洋研究所的 Jean Whelan 博士合作，使用 TG-FTIR 分析了各种石油源岩样品，并将结果与​​成熟度、镜质体反射率、矿物成分、有机物含量和有机成分数据相关联通过标准方法获得。 初步结果表明，TG-FTIR 技术提供了与烃源岩特征相关的有用地球化学信息，包括： a) 独立成熟度指标，即多种有机和无机沉积物成分的 Tmax； b) 有机和无机沉积物碳、氮、硫的物质平衡； c) 沉积有机质干酪根Ⅰ、Ⅱ、Ⅲ类分类及沉积环境数据。 第二阶段将致力于改进设备、方法、使用各种标准材料的校准以及与资源和污染监测相关的各种问题的应用技术。
