Standard Structure and Writing Rules" and SN/T 0001-1995 "Basic regulations for the preparation of pesticides, veterinary drug residues and biotoxin test methods for export commodities" Written by the line. The measurement method is based on the relevant literature at home and abroad, and has been developed after research, improvement and verification. This standard is also formulated Sampling and sample preparation methods. The lower limit of determination is based on the international maximum limit on the amount of oxalochlorone residues in fruits and the sensitivity of the assay. Appendix A of this standard is an informative annex. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted by the Hunan Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Li Yongjun, Huang Zhiqiang, Xiong Fang, Zhang Ying, Dai Hua. This standard is the first industry standard for entry-exit inspection and quarantine. Method for testing oxalicone residues in fruits for import and export1 ScopeThis standard specifies the sampling, sample preparation and gas chromatography-mass spectrometry and confirmation methods for the determination of oxalicone residues in imported and exported fruits. This standard applies to the import and export of citrus and apple oxalic acid residues.2 sampling and sample preparation2.1 Inspection lot No more than 1500 pieces for an inspection lot. Goods in the same inspection lot should have the same characteristics, such as packaging, marking, origin, specifications and grades. 2.2 Number of samples (see Table 1) Table 1 Minimum number of samples in batch 1~25 1 26~100 5 101～250 10 251~1500 15 2.3 Sampling method The number of samples according to 2.2 is randomly selected and opened one by one. Take at least 500g of each piece as the original sample, the total amount of the original sample shall not be Less than 2kg. After the seal, mark the mark and send it to the laboratory in time. 2.4 Sample preparation The original sample was taken out to 1 kg, and the edible portion was taken, crushed by a tissue masher, and divided into two parts, and placed in a clean container as Sample. Seal and mark. 2.5 Sample storage The sample was stored frozen below -18 °C. Note. Samples must be protected from contamination or changes in residue levels during sampling and sample preparation operations.3 Determination method3.1 Method summary The oxaloxan residue in the sample is extracted with benzene-n-hexane and then purified by a small column of activated carbon, using a gas phase with a mass selective detector. The chromatograph was measured and confirmed, and the external standard method was used for quantification. 3.2 Reagents and materials All reagents were of analytical grade and water was distilled water unless otherwise specified. 3.2.1 Benzene. heavy distillation. 3.2.2 n-hexane. heavy distillation. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1115-2002_English be delivered?Answer: Upon your order, we will start to translate SN/T 1115-2002_English as soon as possible, and keep you informed of the progress.
