1 Scope
This standard specifies the foods of animal origin two Trimethoprim (abbreviation. DVD), trimethoprim-sulfamethoxazole (abbreviation. TMP), dimethyl
Oxymethyl trimethoprim (abbreviation. OMP) sample preparation and liquid chromatography sulfa synergist residues - MS/MS detection method.
This standard applies to muscle (pork, chicken), offal (liver, beef kidney, liver), beef fat, eggs, fish, milk and bee products (honey
And royal jelly) in two trimethoprim, trimethoprim-sulfamethoxazole, dimethoxymethyl trimethoprim sulfa synergist three kinds of residues and determination
Confirmed.
2 Method summary
Sample sulfa synergist with triethylamine - acetonitrile mixed extract or trichloroacetic acid - acetonitrile extract, the extract by reverse phase cation
Mixing solid-phase extraction (SPE), concentrated and defatted by liquid chromatography - tandem mass spectrometer and validation, external standard peak area.
