FINNIGAN LCQ ELECTROSPRAY MASS SPECTROMETER

为购买配备电喷雾电离(ESI)和大气压化学电离(APCI)源的四极质谱计和高压液相色谱仪，请从共享仪器赠款计划获得支持。目标仪器--芬兰的一个实验室--将存放在仪器设施中，这是设在化学系的主要仪器的共享核心资源。拟议的ESI/APCI-MSN/DS将是约翰·霍普金斯大学霍姆伍德校区唯一的此类仪器，该大学所有部门的研究小组都可以完全使用。需要使用光谱仪的拟议研究从分子生物学和蛋白质化学延伸到材料科学。

Support is requested from the Shared Instrumentation Grant Program to purchase a quadrupole mass spectrometer and high-pressure liquid chromatograph (HPLC) equipped with Electrospray Ionization (ESI) and Atmospheric Pressure Chemical Ionization (APCI) sources. The target instrument, a Finnigan LCQ, will be housed in the Instruments Facility, a shared core resource for major instrumentation located in the Department of Chemistry. The proposed ESI/APCI-MSn/DS will be the only instrument of its kind at the Homewood Campus of the Johns Hopkins University and will be fully accessible to research groups in all divisions of the University. Proposed research requiring access to the spectrometer extends from molecular biology and protein chemistry to materials science.
