CORE--MASS SPECTROMETRY

描述：质谱学设施和核心提供的服务 支持与环境健康相关的研究的分析能力 OSUEHS中心调查员、计划项目调查员、 和试点项目调查员。核心也是一种教育 化学、生物化学和毒理学研究生的资源。 该设施容纳了六个共享质谱仪和两个原型 乐器。这些为低分辨率GC/MS、高分辨率GC/MS提供了能力 用FAB电离法测量中等尺寸大分子的分辨率 利用化学电离和电子电离的小分子，LC/MS和 电喷雾电离在三重四重质谱仪上的LC/MS/MS 和四重离子陷阱，以及利用基质辅助的高质量分析 激光解吸电离飞行时间质谱仪。

Description: The Mass Spectrometry Facilities and Services Core provides analytical capabilities to support the environmental health-related research projects of the OSUEHS Center investigators, Program Project investigators, and Pilot Project investigators. The Core also serves as an educational resource for graduate students in chemistry, biochemistry, and toxicology. The facility houses six shared mass spectrometers and two prototype instruments. These provide capabilities for low resolution GC/MS, high resolution measurements of medium sized macromolecules using FAB ionization or small molecules using chemical ionization and electron ionization, LC/MS and LC/MS/MS using electrospray ionization on a triple quadruple mass spectrometer and a quadruple ion trap, and high mass analysis using the matrix assisted laser desorption ionization (MALDI) time-of-flight mass spectrometry.
