3 Sample Preparation and Storage
Samples taken in the edible parts of representative about 500g, with the organization stamp mill crushed into a clean container as a sample, seal and make a mark
Knowledge, in the -18 ℃ refrigerator.
Sample preparation process operation should prevent sample contamination or the occurrence of the change of residue content.
4 Method summary
Using ethyl acetate extract samples praziquantel residue, the extract was basic alumina SPE column liquid chromatography - tandem mass spectrometry measurement
Fixed, external standard.
