High performance liquid chromatography mass spectrometer (QqQ)

二维高效液相色谱仪（LC）与灵敏质谱仪（MS）是复杂混合物中化合物定量分析的关键工具，具有较高的选择性和灵敏性。因此，二维液相色谱具有很高的选择性，而质谱仪由于其高分辨率和碎片化实验的使用，可以以极低的检测限对小、中、大分子进行定量。目前，在伍珀塔尔大学的数学和自然科学学院，没有二维（超）高效液相色谱或最先进的质谱仪可用。自从Schebb教授、Bornhorst教授和Simon教授在伍珀塔尔大学开始他们的研究以来，产生了大量的研究问题，这些问题只能通过LC-MS来回答。为了处理新的联合研究项目，工作组决定申请这种制度

Two-dimensional high-performance liquid chromatograph (LC) with a sensitive mass spectrometer (MS) is a key tool for the quantification of compounds in complex mixtures as selective and sensitive as possible. Thereby the two-dimensional liquid chromatography enables a high selectivity, and the mass spectrometer allows the quantification of small, medium and large molecules with extremely low detection limits due to its high resolution as well as the usage of fragmentation experiments. Currently, at the faculty of mathematics and natural science at the University of Wuppertal, no two-dimensional (ultra) high-performance liquid chromatography or a state-of-the-art mass spectrometer are available. Since Prof. Schebb, Prof. Bornhorst and Prof. Simon started their research at the University of Wuppertal a large number of research questions arose, which can only be answered by LC-MS. In order to address new joint research projects, the working groups have decided to apply for such a system
