Hence, it acts to keep the hydronium ion concentration (and the pH) almost constant by the addition of either a small amount of a strong acid or a strong base. If we add a base such as sodium hydroxide, the hydroxide ions react with the few hydronium ions present. naphal receptek

"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. " - Ionization buffer
