Detection of residual parameters of animal food/veterinary drugs

National Food Safety Standard for the Determination of Multiple Residues of Lincomycin, Clindamycin, and Spectinomycin in Animal Food - Gas Chromatography-Mass Spectrometry Scope 1 This standard specifies the preparation of samples and the gas chromatography-mass spectrometry method for the detection of Lincomycin, Clindamycin, and Spectinomycin residues in animal food. This standard is applicable to the detection of single or multiple drug residues of lincomycin, clindamycin, and spectinomycin in the muscles and kidneys of pigs, cows, and chickens, as well as in milk and eggs. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated reference documents, the latest version (including all modifications) is applicable to this document. GB/T 6682 Analytical Laboratory Water Specification and Test Method 3: Residual Lincomycin, Clindamycin, and Spectinomycin in Principle Test Materials, extracted with phosphate buffer, precipitated with 3% trichloroacetic acid protein, purified with ion pair principle reverse phase SPE column, derived with N, O-bis (trimethylsilyl) trifluoroacetamide, and determined by gas chromatography-mass spectrometry, Quantitative analysis using external standard method
