本人在用Q-E的液质做一些关于脂质组学方面的内容,从文献上看到几句话不太懂,希望能请教一下各位大神们。MS1 spectra were acquired under operator control with target mass resolving power ofRP= 70,000 at m/z 200 to distinguish precursor ions ofmolecular species with similar m/zvalue, and MS2 spectra were acquired with target mass resolving power of RP= 17,500 at m/z 200 为什么设置分辨率的时候后面要带上at m/z 200 这个东西,着实不懂。
