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. WebIt is a buffer because it contains both the weak acid and its salt. 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.
