Ionization buffer

WebIonization interferences may also be found in AAS, e.g. when measuring certain Group II elements in a nitrous oxide flame. An ionization buffer such as Cs, Li or K can be added to both samples and standards to minimize this effect. Spectral The optical requirements of AAS are fairly simple. http://delloyd.50megs.com/moreinfo/AAinterferences.html

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.
