WebA spectrogram is a hybrid between an FFT and a time domain graph- it shows how the spectral content of the vibration changes over time. Spectrograms are especially useful for analyzing quasi-periodic vibrations (like those in music and human speech). WebThe whole point of mass spectrometry is to separate ions based on their mass. Ions need to be accelerated or else they wouldn't be able to reach the detector at the end of the …
