mass spectrum

…able to scan through a mass spectrum and measure a current corresponding to each separated ion species. Thus he may be credited with the construction of the first mass spectrograph and the first mass spectrometer.

…abundance is known as a mass spectrum. From the masses and abundance of the peaks in a mass spectrum, it is often possible to determine the exact mass of the molecule being analyzed and to obtain clues about molecular structure. Today chemists can use one of several different types of…
