Özet
This study proposed a precise/accurate analytical method for the paracetamol (PCT) determination in human serum/urine matrices. PCT was simultaneously derivatized and preconcentrated by dispersive liquid-liquid microextraction (DLLME). Benzoyl chloride dissolved in dichloromethane was used as derivatization agent in the extraction solvent. Quadruple isotope dilution (QID) method with three calibration mixtures (A*B-x, x=1,2,3) and one sample mixture (AB) was performed to enhance the method accuracy and precision. In our research laboratory, paracetamol benzoate-d3 (PCT benzoate-d3) was synthesized and used as isotopically labelled substance (B) to conduct QID method. After the combination of QID and DLLME-GC-MS systems, percent recovery results for human serum/urine matrices were found to be 99.3-101.0 % and 98.8-99.9 %, respectively.
