| Similar to amass spectrometer, mass spectrograph is an instrument used to obtain mass spectra. In the mass spectrograph, ions with different m/z values are passed through a magnetic sector and dispersed in different trajectories similar to the dispersion of different wavelengths of light in a prism. The ions separated according to their m/z values are directed onto the same face and are simultaneously detected by a focal plane detector. This mass spectrum-measurement system is unique for instruments called as “mass spectrographs.” However, m ny mass spectrometrists refer to instruments that should be called “mass spectrometers” as “mass spectrographs.” | ||
