Characterization of Fe, Ni, Pb Standard Solution using One-point Calibration Methods

Abstract Calibration of measurement systems using well-prepared calibration materials is an important means of making traceability in chemical measurements. Traceability is established through the use of measurement standards (such as certified reference materials) that are appropriate for each parameter. Pure substance certified reference materials such as elemental standard solutions are the most commonly used for calibration, called external calibrations using one, two or multiple standards. In this study, one-point calibration method has been applied for characterizing of Fe, Ni and Pb standard solutions. The results show that the concentration of the Fe, Ni and Pb standard solutions with their relative uncertainties were found to be 997.81 ± 6.34 mg/kg, 997.61 ± 8.10 mg/kg, 1004.29 ± 8.62 mg/kg, respectively.
