分析化学设施核心由质量 光谱实验室和金属分析实验室。金属分析 在NIEHS中心最后一次拨款更新之前， 1995.质谱（MS）实验室提供分析方法， 确定化学结构和识别化学成分的数据 混合物。低分辨率和高分辨率MS仪器均采用 各种样品引入技术（例如气相色谱和质谱） 光谱法、快原子轰击法和直接探针法）和电离法 （电子碰撞和化学电离）。原子吸收（AA） 实验室提供各种基质中金属的分析。样品 制备实验室包含两个HPLC系统。的主任 实验室具有NMR技术的经验，并已安排提供NMR 分析和数据解释。向中心提供的服务清单 表明MS和AA分析占主导地位。

The Analytical Chemistry Facility Core is composed of a Mass Spectrometry Laboratory and a Metals Analysis Laboratory. The Metal Analysis lab was added to the facility prior to the last NIEHS Center grant renewal in 1995. The Mass Spectrometry (MS) laboratory provides analytical methods and data to determine chemical structure and to identify components in chemical mixtures. Both low and high resolution MS instruments are employed with a variety of sample introduction techniques (e.g. gas chromatography and mass spectrometry, fast atom bombardment, and direct probe) and ionization methods (electron impact and chemical ionization). The Atomic Absorption (AA) laboratory provides analyses of metals in a variety of matrices. A sample preparation laboratory contains two HPLC systems. The director of the laboratory has experience with NMR techniques and has arranged to provide NMR analyses and data interpretation. The list of services provided to the Center indicates that MS and AA analyses predominate.
