Wool test sampling method
3 principle
3.1 poison kill Fen, pyrethroid
The sample was extracted with n-hexane ether solvent, the extract was purified by neutral alumina solid-phase extraction column and Florisil solid-phase extraction column
Using gas chromatography - electron capture detector determination, retention time qualitative, external standard method.
3.2 Organic phosphorus
The sample was extracted with n-hexane ether solvent, and the extract was purified by neutral alumina solid-phase extraction column and analyzed by gas chromatography-nitrogen and phosphorus
Detector to qualitative retention time, external standard method.
