Foreword

The Standard Appendix A and Appendix B is an informative annex. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard by the Chinese Academy of Inspection and Quarantine, Shenzhen People's Republic of China Exit Inspection and Quarantine is responsible for drafting. The main drafters of this standard. Peng Tao, Yu Jing, Li Xiaojuan, Yuezhen Feng, Li Jianzhong, Guo Wei, Tang Ying Zhang, Chu Xiaogang. This standard is the first release of the entry-exit inspection and quarantine industry standards. Import and export of animal-derived foods acetaminophen, O-acetylsalicylic acid residues in the detection method Liquid chromatography - mass spectrometry/mass spectrometry

1 Scope

This standard specifies the paracetamol, o-acetylsalicylic acid residues in food of animal origin liquid chromatography on - mass spectrometry/mass spectrometry. This standard applies to animal tissues, organs, eggs and milk to detect acetaminophen, o-acetylsalicylic acid residues.

2 Sample Preparation and Storage

2.1 animal tissues and organs Samples taken from the original representative sample of about 500g, with a full organization stamp mill crushed mix, are divided into two, respectively, into a clean container As a sample, sealed and marked with tags. The sample was placed in -18 ℃ freezer stored. 2.2 Egg Samples taken from the original representative sample of about 500g, peeled with a tissue after stirring thoroughly mixed stamp mill, are divided into two, respectively, into Clean as a sample container, sealed and marked with tags. The sample was placed at 4 ℃ stored. 2.3 milk Samples taken from the original representative sample of about 500g, with a stamp mill and mix well organized, are divided into two, respectively, into a clean container for As a sample, sealed and marked with tags. The sample was placed at 4 ℃ stored. In the sample preparation procedure, it should prevent sample contamination or the occurrence of the change of residue content.

3 Method summary

Samples were extracted with acetonitrile residual acetaminophen, o-acetylsalicylic acid (marker residue. salicylic acid), the n-hexane to remove fat, After the solid-phase extraction (SPE), liquid chromatography - mass spectrometry/mass spectrometry, external standard.
