Foreword

The revised standard 995.09 "edible animal tissues oxytetracycline, tetracycline, chlortetracycline residues were measured using standard AOAC Phase chromatography. " The main technical differences compared to the standard and AOAC standards are as follows. --- C18 solid phase extraction column to OasisHLB SPE. --- Eluent from methanol to ethyl acetate. --- Increased acid cation exchange column purification. --- Increased determination varieties. The Standard Appendix A, Appendix B is an informative annex. This standard is proposed and managed by the State Administration of Quality Supervision, Inspection and Quarantine. This standard was drafted. People's Republic of China Qinhuangdao Exit Inspection and Quarantine. The main drafters of this standard.
