基质解析-飞行时间质谱教程
Mass spectrometers provide the ability to accurately measure the mass of almost any molecule that can be ionised to the gas phase. A
mass spectrometer consists of three essential components (Fig. 1.1.); an ion source, a mass analyser and a detector. An ion source
converts molecules into gas-phase ions. Once these ions are created, they are separated in the mass analyser by their mass (m) to
charge (z) ratio and detected by an electron multiplier. MS data are recorded as ‘spectra’ which display ion intensities versus their m/z
value.
