Mass spektrometer with electrospray ionisation

我们申请了一台高分辨率电喷雾电离质谱仪(ESI-MS)和一台四极轨道分析器，用于MS/MS模式。除了相关的EDV外，还需要一台高效液相色谱仪作为外围设备，以实现LC-MS光谱的测量。整套设备还包括ESI运行所需的氮气发生器(因为通过压缩气瓶供应在高流量下是不经济的)、不间断电源(USV，由于建筑物频繁的计划外和计划内停电)和真空泵的隔音。申请的装置专门用于有机和无机分子化合物的质谱分析研究，这些化合物通常是新的合成产品。此外，还需要LC-MS联用来研究复杂的产物或反应混合物，以便识别产物和副产物，例如，可以用来优化反应或建立反应机理。需要MS/MS联用来阐明意外的和未知的化合物(可能来自使用LC-MS的混合物)的结构(组成)。

We apply for a high-resolution mass spectrometer with electrospray ionization (ESI-MS) and a quadrupole orbitrap analyzer for operation in MS/MS mode. In addition to the associated EDV, an HPLC is requested as a peripheral device, which enables the measurement of LC-MS spectra. The complete package also includes a nitrogen generator required for ESI operation (since supply via compressed gas cylinders would be uneconomical at high flow rates), an uninterruptible power supply (USV, due to frequent unplanned and planned power shutdowns in the building) and noise insulation for the vacuum pump. The device applied for is used exclusively in research for the mass spectrometric analysis of organic and inorganic molecular compounds, which are usually new synthetic products. In addition, LC-MS coupling is required to investigate complex product or reaction mixtures in order to identify products and by-products, which can be used, for example, to optimize the reaction or to establish reaction mechanisms. MS/MS coupling is required to elucidate the structure (constitution) of unexpected and unknown compounds (possibly from mixtures using LC-MS).
