The Generalized Standard Addition Method.

The normal standard addition methods assumes that, for any one analyte in a sample there is an analytical sensor which responds to that analyte and no other unknown in the sample. When the analytical sensor is not completely selective, so-called interference effects results which can be a major source of error. The generalized standard addition method provides a means of accounting for the interference effects, to actually quantify the magnitude of the interferences, and simultaneously to determine the analyte concentrations.
