Spectral Interference: Types, Avoidance and Correction

Avoidance: ICP-OES

Several modern ICP instruments have the capability of avoiding the spectral interference by going to another line. Many instruments can make measurements simultaneously on several lines for 70+ elements in the same time it used to take to make a measurement on a single line/element combination. If you have the opportunity, I would strongly encourage the avoidance approach over attempting to make correction on a direct spectral overlap or wing overlap interference. Background corrections are another manner and can be routinely dealt with.
