Scope
Scope: This standard specifies the method for determining the residual amount of ketoconazole in tea and tea leaves by liquid chromatography-mass spectrometry/mass spectrometry. This standard is applicable to the routine monitoring and risk assessment of ketoconazole residues in tea and tea leaves produced by members of the Guizhou Provincial Green Tea Brand Development Promotion Association; Main technical content: The residual ketoconazole in the sample is extracted with acetonitrile-acetic acid solution, purified by a solid-phase extraction column, and determined by liquid chromatography-mass spectrometry/mass spectrometry, with quantification performed using the external standard method.
