high resolution mass spectrometer with gas chromatograph and direct probe inlet system

对于小的非极性化合物的物质混合物的分析，气相色谱与电子碰撞电离的组合是表征新合成化合物和探索新合成路线的基本分析方法。因此，从高分辨率质谱中，不仅可以确定分子量，还可以确定有关物质的元素组成和结构的重要信息。在达姆施塔特技术大学化学系的质谱分析核心设施中，缺乏一台用于研究非极性物质混合物的现代质谱仪。因此，采购一台高分辨率质谱仪，它能够进行电子碰撞电离（EI）和化学电离（CI），并与现代气相色谱仪和直接探针入口系统相结合，对于高精度分析质量高达2000道尔顿的小非极性分子至关重要，这些分子主要在有机，大分子和技术化学中合成。

For the analysis of substance mixtures of small, non-polar compounds the combination of gas chromatography together with electron impact ionization is an essential analytical method for characterizing newly synthesized compounds and exploring new synthetic routes. Thus, from high resolution mass spectra, not only the molecular weight can be determined, but also important information about the important information on the elemental composition and structure of the substances. In the core facility for mass spectrometry of the chemistry faculty of the Technical University of Darmstadt lacks a modern mass spectrometer for the investigation of non-polar substance mixtures. Therefore, the procurement of a high-resolution mass spectrometer, which is capable of electron impact ionization (EI) and chemical ionstaion (CI) and is also coupled with a modern gas chromatograph and a direct probe inlet system is essential for the high-precision analysis of small nonpolar molecules with a mass of up to two thousand daltons, which are synthesized mainly in organic, macromolecular and technical chemistry.
