SummaryCalibration of solid sampling Zeeman AAS for cadmium was investigated. A series of certified reference materials was analysed using a CRM with a different composition as standard. For routine applications this yielded satisfactory results. A method of calibration was then applied involving addition of standard solution to lyophilized samples, followed by lyophilization and homogenization. Using an iteration procedure results were obtained which no longer depend on certified reference… CONTINUE READING
