Tandem mass spectrometer coupled to a ultra-high performance liquid chromatograph

将采购一个由超高效液相色谱仪和具有线性离子阱和电喷雾电离的三重四极杆质谱仪组成的系统。色谱系统应包括一个二元高压泵、一个温控柱恒温器、一个自动进样器和一个温控进样器。串联质谱仪应具有尽可能高的灵敏度，以便能够分析浓度极低的化合物。此外，应给出通过所谓的多反应监测（MRM）模式定量化合物的可能性。出于这个原因，打算获得具有线性离子阱的混合三重四极质谱仪。整个系统的另一个重要组成部分是一个功能强大的软件，可以对测量数据进行可靠的解释。该系统将主要用于小分子、多肽和蛋白质的靶向分析。此外，该系统将用于表征生物活性食品成分及其代谢产物，并表征碳水化合物的反应产物。

A system consisting of an ultra-high performance liquid chromatograph and a triple quadrupole mass spectrometer with linear ion trap and electrospray ionization is to be procured. The chromatographic system should consist of a binary high-pressure pump, a temperature-controlled column thermostat, an automatic sampler, and a temperature-controlled sampler. The tandem mass spectrometer shall have the highest sensitivity possible to make the analysis of very low concentrated compounds possible. Furthermore, the possibility of quantifying compounds by means of the so-called multiple reaction monitoring (MRM) mode should be given. For this reason, the acquisition of a hybrid triple quadrupole mass spectrometer with linear ion trap is intended. Another important component of the overall system is a powerful software that allows a reliable interpretation of the measurement data. The proposed system will be used mainly for the targeted analysis of small molecules, peptides and proteins. In addition, the system will be used to characterize bioactive food ingredients and their metabolites and to characterize reaction products from carbohydrates.
