WebAdding an ionization buffer can help to mitigate the ionization effects for some elements. In the case of organic samples, oxygen (present in compressed air) can be added into … WebCs is often used as an ionization buffer with axial view ICP-OES for the determination of the lighter alkalis (usually Li, Na, and K). However it must be very pure, as in Inorganic Ventures' 1% Cesium Ionization Buffer. ICP-MS is often the recommended technique for the determination of Rb and Cs where detection limits in the ppq region are common.

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.
