http://delloyd.50megs.com/moreinfo/AAinterferences.html WebIonization buffers are used for the suppression of physical, ionic, and chemical interferences for use with flame atomic absorption spectroscopy. These are buffers added to increase the free-electron concentration by the flame gases, thus repressing and stabilizing the degree of ionization.
