High performance liquid chromatography mass spectrometer (QqQ)

带有灵敏质谱仪(MS)的二维液相色谱(LC)是尽可能选择性和灵敏地定量复杂混合物中化合物的关键工具。因此，二维液相色谱实现了高选择性，质谱仪由于其高分辨率以及使用裂解实验而允许以极低的检测限定量小、中和大分子。目前，在伍珀塔尔大学的数学和自然科学学院，还没有可用的二维(超)高效液相色谱仪或最先进的质谱仪。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，出现了大量的研究问题，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，工作组决定申请这样一个系统

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
