Triple Quadrupol LC/MS-System

购买三重四极杆LC/MS系统，用于定量测定和分析小有机分子和高电荷分子（例如核苷酸，如二核苷多磷酸盐、修饰的RNA结构单元），部分是在细胞裂解物的复杂混合物中。所要求的MS系统是为了取代现有系统，该系统多年来已变得非常容易出错和需要大量维护。所要求的仪器系统旨在升级化学系对复杂混合物进行质谱分析的方法。

A triple quadrupole LC/MS system is to be purchased for the quantitative determination and analysis of small organic molecules and highly charged molecules (e.g. nucleotides such as dinucleoside polyphosphates, modified RNA building blocks), in part in complex mixtures of cell lysates. The requested MS system is to replace the existing system, which has become very error-prone and maintenance-intensive over the years. The requested instrument system is intended to upgrade the methods performed at the Department of Chemistry for mass spectrometry-based analysis from complex mixtures.
