Detection in food import and export of avermectin residues
High performance liquid chromatography - mass spectrometry/mass spectrometry
1 Scope
This standard specifies the foods HPLC avermectin residues - MS/MS detection method.
This standard applies to rice, garlic, spinach, apples, chestnuts, tea, beef, lamb, chicken, fish, red peony root, vinegar and honey Avi
Avermectin residues detected.
2 Method summary
After the first sample honey and vinegar diluted with water to a C18 solid phase extraction (SPE); other samples were extracted with acetonitrile, the solid phase with neutral alumina
Extraction (SPE), high performance liquid chromatography - mass spectrometry/mass spectrometry, external standard.
