Where can I check ab mass spectrometry?

Ab is displayed in the form of mass spectrometry after computer processing.

In the mass spectrogram, the abscissa represents the mass-to-charge ratio (m/z) of ions, and the value of the mass-to-charge ratio increases from left to right. For ions with a single charge, the value represented by the abscissa is the mass of the ion. The ordinate represents the intensity of ion current, which is usually expressed by relative intensity.
