项目概要/摘要（开发核心） 开发核心（DC）和非目标分析资源核心（UARC）将与 总体目标是增加被检测和识别的分析物或生物标志物的范围， 环境暴露。DC将与UARC的大数据分析部门合作， 化合物.除了已经存在的基质外，DC还将优化新基质的提取程序 分析（例如，尿液、血清、血浆、粪便、唾液和汗液），并将对生物样本进行分析 在不同条件下收集和储存，为流行病学研究提供最佳做法。他们将 建立了一种非靶向方法，使用气相色谱法耦合到轨道阱质谱仪（GC-Q-）， Exactive），以扩大UARC提供的服务。DC还将使用GC和液相色谱法 采用多反应监测（MRM）和MSn的（LC）-质谱法，以开发特定的宽 光谱板，用于快速定量分析难以在非靶向物质上检测的分析物 平台DC将由Timothy Fennell博士（MPI，RTI）指导，他在以下方面拥有丰富的经验： 化学品接触、代谢物鉴定和毒性以及接触生物标志物的开发。

Project Summary/Abstract (Development Core) The Development Core (DC) and the Untargeted Analysis Resource Core (UARC) will collaborate, with the overall aims to increase the range of analytes or biological markers that are detected and identified that reflect environmental exposures. The DC will work with the Big Data Analytics of UARC to prioritize the sourcing of compounds. The DC will optimize extraction procedures for new matrices, in addition to the matrices already analyzed (e.g., urine, serum, plasma, feces, saliva and sweat), and will conduct analyses of biospecimens collected and stored under different conditions to inform best practices for epidemiology studies. They will establish an untargeted method using gas chromatography coupled to an orbitrap mass spectrometer (GC-Q- Exactive) to expand the services offered by the UARC. The DC will also use GC- and liquid chromatography (LC)-Mass spectrometry with Multiple Reaction Monitoring (MRMs) and MSn to develop specific broad spectrum panels for rapid quantitative analysis of analytes that are difficult to detect on the untargeted platforms. The DC will be directed by Dr. Timothy Fennell (MPI, RTI), who has extensive experience with chemical exposure, metabolite identification and toxicity, and exposure biomarker development.
