This standard is the first release of the entry-exit inspection and quarantine industry standards. Imported and exported food veracity and detection of pesticide residues Gas chromatography - mass spectrometry1 ScopeThis standard specifies the sample preparation and GC foods propynyl amine fluoride grass residues - mass spectrometry methods. This standard applies to apples, spinach, ginger, fish, chicken, pork, soybeans, rice, almonds and liver in veracity and detection of pesticide residues. 2. Sample Preparation and Storage 2.1 soybeans, rice and almonds Take a representative sample of 500g, all crushed and allowed to 2.0mm pore size of the sieve sample. After mixing are divided into two, installed Inside into clean containers, seal and logo; -4 ℃ kept in the dark. 2.2 spinach, apple and ginger Take a representative sample of at least 500g, will take their edible parts cut into small pieces using tissue samples were homogenized broken machine, after mixing into Two, into a clean sample bags, sealed and identifies; saved in -18 ℃ in the dark. 2.3 fish, chicken, pork and liver Take a representative sample of at least 500g, chopped and dried edible parts take tissue samples were homogenized stamp machine, mixed evenly divided into two charged Clean sample bags, sealed and identifies; saved in -18 ℃ in the dark. In the sample preparation procedure, it should prevent sample contamination or the occurrence of the change of residue content.3 Method summaryThe sample was extracted with ethyl acetate or acetonitrile, an amino solid phase extraction (SPE), and concentrated eluate volume by gas chromatography - mass spectrometry and selected from Sub measured monitoring mode, external standard.4 Reagents and materialsUnless otherwise specified, all reagents were of analytical grade water as distilled water or ion exchange water. 4.1 acetonitrile. chromatography. 4.2 Toluene. chromatography. 4.3 ethyl acetate. 4.4 n-hexane. 4.5 veracity and alachlor (Flumioxazin, CH15FN2O4, CAS.No. 103361-09-7) Standard. purity of greater than 99%. 4.6 anhydrous sodium. 650 ℃ burning 4h, stored in a sealed container in the back. 4.7 acetonitrile saturated with n-hexane. Take a small amount of acetonitrile was added n-hexane, shaken vigorously and continue to acetonitrile significant stratification, standing spare. 4.8 LC-NH2 Amino-SPE. 3mL, 0.5g or equivalent person. 4.9 veracity and alachlor standard solution. Accurately weigh an adequate amount of veracity and alachlor standards, formulated with acetonitrile to a concentration of 100μg/mL standard Quasi-stock solution, this solution was stored in a brown flask and stored at 0 ℃ ~ 4 ℃ condition. Stock solution and then diluted with acetonitrile required to prepare An appropriate concentration of the standard working solution, kept at 0 ℃ ~ 4 ℃ condition. 4.10 standard solution matrix. Matrix standard solution is an appropriate amount of veracity and alachlor standard solution, equipped with a blank matrix extract An appropriate concentration of the standard substrate working solution. Matrix standard working solution should now use the existing. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1983-2007_English be delivered?Answer: Upon your order, we will start to translate SN/T 1983-2007_English as soon as possible, and keep you informed of the progress.
