Development and validation of a liquid chromatographic method for the determination of nitrofuran residues in fish samples

Abstract

A sensitive, accurate and efficient liquid chromatographic method has been developed for determination of nitrofuran residues in a honey sample; It was found that the detection minimum for all four nitrofuran group substances is 0.03 μg / ml, the specific wavelength is 376 nm, the specificity coefficient of variation for both on one working day and one working week is 0.99); Sample preparation is satisfactory as the obtained sampling coefficient is> 0.6. Thus, as a result of validation of the liquid chromatographic method developed for the quantitative determination of nitrofuran residues in the honey sample, the method was fully complied with the requirements of the Government of Georgia according to the following validation characteristics: detection minimum, specificity, accuracy, correctness and linearity.
