Abstract

SPECTROPHOTOMETRY


Objectives: The aim of this study was to develop and validate the plasma copper quantitation method by graphite furnace atomic absorption spectrophotometry. Method: The limit of detection, limit of quantitation, linear range, precision and accuracy of the plasma copper quantitation by GFAAS were evaluated. Results: The LOB, LOD and LOQ of this method were 0.44 µmol/L, 1.06 µmol/L and 2µmol/L respectively. The method linearity was from 2 to 50 mmol/L. The repeatability at the concentrations of 11.7 and 21.3 (mmol/L) were 3.09 and 2.14 (%) respectively. The reproducibility at the two concentrations above were 6.68 and 4.68 (%) respectively. The recovery of spiked samples were 108.5; 102.8; và 94.3 %,  fell in range of  80-110%;  acceptable following the AOAC 2016 criteria. Conclusion: The developed direct method for plasma copper quantitation by GFAAS was accurate and precise, can be used for diagnosis and treatment monitoring of copper metabolism disorders.
