This grant support acquisition of a new bench-top gas chromatograph-mass spectrometer (GC-MS) for biomarker research at Indiana University. The GC-MS will be dedicated to analyses of molecular constituents in geological samples that can provide invaluable clues to the diverse origins and varied fates of sedimentary organic matter. It will replace aged, high-maintenance GC-MS instrumentation that is at the end of its useful lifespan. Graduate and undergraduate students, and also visiting scientists, will be trained in its operation, learning how to identify organic compounds amid complex mixtures, and will use the results from their analyses in a broad spectrum of projects. Data obtained using this GC-MS instrument, coupled with information on isotopic compositions, will enhance research focused on understanding the numerous controls on molecular and isotopic compositions of earth materials. The results from such biogeochemical research will benefit understanding of the history of global climate and environmental change, the biogeochemical carbon cycle, microbial activity and the deep biosphere, and evolutionary processes.

这项赠款支持获得印第安纳大学生物标志物研究的新台式气体色谱质质谱仪（GC-MS）。 GC-MS将致力于分析地质样本中分子成分的分析，这些分子成分可以为沉积有机物的各种起源和各种命运提供宝贵的线索。它将取代其有用寿命结束时老化的高维护GC-MS仪器。 研究生和本科生，以及访问的科学家将接受其运作培训，学习如何在复杂的混合物中识别有机化合物，并将在各种项目中使用其分析结果。使用此GC-MS仪器获得的数据，再加上同位素组成的信息，将增强专注于了解地球材料分子和同位素组成的众多控制的研究。这种生物地球化学研究的结果将使人们对全球气候和环境变化的历史，生物地球化学碳循环，微生物活性和深层生物圈以及进化过程的了解有益。
