WebbSeveral flaws of the conventional standard-addition method (SAM) have been unravelled. By revisiting the theory, it has been shown that the SAM cannot be used to correct completely for interferences in analytical chemistry. WebbStandard additions is a calibration technique devised to eliminate rotational matrix effects in analytical measurement. Although the technique is presented in almost every textbook of analytical chemistry, its behaviour in practice is not well documented and is prone to attract misleading accounts.
