ENVIRONMENTAL HEALTH APPLICATIONS OF MASS SPECTROMETRY

质谱使命的组成部分之一 是为LMB和NIEHS中的其他团体提供大量 基于服务的光谱分析。 该公司提供 持续提供以下服务：1）低和高 分辨率电子轰击（EI）质谱; 2）低和高 分离化学电离（CI）质谱; 3）负离子 化学电离（NICI）质谱：4）气相色谱/质谱 质谱法（GC/MS）结合EI、CI和NICI MS; 5） 热喷雾（TSP）液相色谱/质谱（LC/MS） 结合CI和NICI MS; 6）快原子轰击（FAB） 在正离子和负离子条件下; 7）连续流 FAB/MS和FAB/MS/MS在正负离子下 条件;和8）串联MS与阳性和 负离子FAB、EI和CI MS。 在过去的一年中，进行了大约691次分析。 以服务为基础（不包括协作工作）。

One of the components of the mass spectrometry workgroup mission is to provide other groups within LMB and 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 chemical ionization (CI) mass spectra; 3) negative ion chemical ionization (NICI) mass spectra: 4) gas chromatography/mass spectrometry (GC/MS) in conjunction with EI, CI and NICI MS; 5) thermospray (TSP) liquid chromatography/mass spectrometry (LC/MS) in conjunction with CI and NICI MS; 6) fast atom bombardment (FAB) under both positive and negative ion conditions; 7) continuous flow FAB/MS and FAB/MS/MS under both positive and negative ion conditions; and 8) tandem MS in combination with positive and negative ion FAB, EI and CI MS. During the past year approximately 691 analyses have been performed on a service basis (not including collaborative work).
