MALDI Time-of-Flight Mass Spectrometer

新型功能聚合物、低聚物和模型化合物的合成、表征和应用是拜罗伊特大学聚合物和胶体研究以及SFB 840和SFB 1357剖面场研究的中心领域。在这种情况下，对这些材料的化学结构的精确知识，包括分子量、分子量分布以及通常是端基的化学结构，对于基础研究是必不可少的。对于分子量的表征，我们目前只有凝胶渗透色谱(GPC)作为一种成熟的方法。对于MALDI-MS分析，我们过去使用的是MALDI-TOF光谱仪Bruker Reflex III™。这台光谱仪是2001年购买的。在过去的几年里，这台仪器有几个缺陷，因此几乎无法使用。由于没有备件供应，制造商也没有更多的服务，因此更换旧的光谱仪是必不可少的。对于本提案中提到的研究项目，MALDI-TOF光谱仪在化学领域是不可或缺的。

The synthesis, characterization, and application of novel functional polymers, oligomers and model compounds is a central research area of the profile field Polymer and Colloid Research at the University of Bayreuth as well as of the SFB 840 and SFB 1357. In this context, precise knowledge of the chemical structure of these materials, including molecular weight, molecular weight distribution and often the chemical structure of the end groups, is indispensable for fundamental investigations. For the characterization of molecular weight, we currently have only gel permeation chromatography (GPC) as an established method. For MALDI-MS analyses we used a MALDI-ToF spectrometer Bruker Reflex III™ in the past. This spectrometer was purchased in 2001. During the last years, the instrument had several defects and therefore was hardly usable. Since there is no spare part supply and no more service from the manufacturer, a replacement of the old spectrometer is indispensable. For the research projects mentioned in this proposal, a MALDI-ToF spectrometer is indispensable in the field of chemistry.
