1 Scope
This standard specifies the sampling, sample preparation and testing of artificial synthetic hormones estrone, diethylstilbestrol and diethylstilbestrol in animal feed.
Gas chromatography-mass spectrometry.
This standard applies to the test of residues of hexestrol, diethylstilbestrol and diethylstilbestrol in animal feed.
2 sampling and sample preparation
2.1 Inspection lot
No more than.2000 pieces for one 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
The number of samples is shown in Table 1.
Table 1
Batch/piece minimum sample/piece
1 to 500 15
501~1000 25
1001～2000 35
2.3 Sampling tools
2.3.1 Sampling spoon.
2.3.2 Sample plate.
2.3.3 Sample cloth.
2.3.4 Sample holder. tube or bag, can be sealed.
2.4 Sampling methods
The sample bags are randomly taken from each part of the stack according to the number of samples to be sampled according to 2.2, and opened one by one. Extract the representative from each sample with a sampling spoon
The sample was 500 g and immediately placed in a clean sample holder. The total amount of sample taken per bag should be no less than 4kg.
Pour all the samples taken onto the sample cloth, and use the sample plate to divide the sample into not less than 2 kg by quarter method. Pour into the sampler and seal
After that, mark the mark and send it to the laboratory in time.
2.5 Sample preparation
2.5.1 Sample preparation tools
a) Crusher.
b) Sample plate.
c) Sample holder. with a jar or sealed bag.
2.5.2 Sample preparation method
The retrieved samples were all pulverized, mixed, and evenly divided into two portions by a quarter method, and placed in a sample holder as a sample. Seal and mark the mark.
2.6 Sample storage
The sample was sealed and stored at 5 ° C or lower. Samples should be protected from contamination or residue levels during sampling and sample preparation.
