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 spectrometry
1 Scope
This 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 summary
The 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 materials
Unless 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.
