How the peptides ion are isolated via mass to charge ratio value ?

Electrospray Ionization (ESI) is a method by which solutes present in a solution can be transferred into the gas phase as ions. In that case the analyte is charged by association w...

In 1913, Thomson measured the mass-to-charge ratio of ions with an instrument he called a parabola spectrograph. Today's mass spectrometer. Typically, mass spectrometers measure th...
