ENVIRONMENTAL HEALTH APPLICATIONS OF MASS SPECTROMETRY

质谱学工作组的任务之一是 为NIEHS内的其他小组提供对以下内容的质谱分析 以服务为基础。工作组在网上提供以下服务 正在进行的基础：1)低分辨率和高分辨率电子碰撞(EI)质量 2)低分辨和高分辨化学电离(CI)质谱图； 3)负离子化学电离(NICI)质谱图；4)气体 气相色谱/质谱仪(GS/MS)与EI、CI和 NICI MS；5)热喷雾(TSP)液相色谱/质谱法 (LC/MS)与CI SNF NICI MS联用；6)电喷雾电离 (ESI)MS与毛细管电泳联用和纳米级填充LC；7) 正负离子下的快原子轰击(FAB) 8)连续流动FAB/MS和FAB/MS/MS 负离子条件；9)串联质谱结合正离子和 负离子FAB、ESI、EI和CI MS我们还提供高性能 高效液相色谱法和毛细管区带电泳法 支持。 在过去的一年里，大约进行了900次MS分析 服务基础(不包括协作工作)。

One of the components of the mass spectrometry workgroup's mission is to provide other groups within NIEHS access to mass spectrometric analyses on a service basis. The workgroup provides the following services on an ongoing basis: 1) low and high resolution electron impact (EI) mass spectra; 2) low and high resolution chemicals ionization (CI) mass spectra; 3) negative ion chemical ionization (NICI) mass spectra; 4) gas chromatography/mass spectrometry (GS/MS) in conjunction with EI, CI, and NICI MS; 5) thermospray (TSP) liquid-chromatography/mass spectrometry (LC/MS) in conjunction with CI snf NICI MS; 6) electrospray ionization (ESI) MS coupled with capillary electrophoresis and nanoscale packed LC; 7) fast atom bombardment (FAB) under both positive and negative ion conditions; 8) continuous flow FAB/MS and FAB/MS/MS under both positive and negative ion conditions; and 9) tandem MS in combination with positive and negative ion FAB, ESI, EI and CI MS. We also provide high performance liquid chromatography (HPLC) and capillary zone electrophoresis (CZE) support. During the past year approximately 900 MS analyses have been performed on a service basis (not including collaborative work).
