Samples for mass analysis are ionized, for example by laser ( matrix-assisted laser desorption / ionization ) or discharge ( electrospray or inductively coupled plasma ) and the resulting beam is sent through the RFQ and " filtered " by scanning the operating parameters ( chiefly the RF amplitude ).
