4.1 Sampling
According to the "sampling method of milk reduction and body state" in GBT[635~-1E7(80>, the packaging of random number sampling is determined, and the minimum sampling volume should be not less than 20mL. 4.2 Specific test
4. 2.1 The relative colorimetric method can be used to determine the sugar content of the sample at the same time. In the relative colorimetric conditions, the sample is kept in the same color as the standard sample for a period of time. The relative value is within 1.2.2 Infrared spectroscopy: The infrared spectrum of the sample with a high concentration of 400-30Dcm·m has obvious differences with the standard sample. The infrared spectrum of the sample with a concentration of 1,4300
is due to the monoamine ion. 4.3. Determination of the content of butachlor in blood and pancreas Abstract The test sample was dissolved in trioxygen medium with trioxygen as internal standard. A 55E-/CrmOb material AwDMCS(1B0253> was used as the filler material in a stainless steel cell. The test sample and the components were separated and determined by gas phase micro-separation. 4.3.2 Reagents: Trichloromethane. Sample: The amount of butachlor was known in large quantities. The internal standard should be diphenyl ether with no salt interfering with the analysis. Take out the sample of SE30 and get DMc5 (15C-250μml internal standard concentrate; take 2.D g of phosphorus thiocyanate by pulse, put it into 1 mL of liquid, add appropriate amount of oxymethoxybenzene, and dilute to the concentration of 1% chlorinated protein, shake.

4.3.4.1 Preparation of fixed solution
Weigh 3.55V-30 fixed solution in 250mL of calcined water, add appropriate amount (slightly) of carrier wood > trioxygen to make it completely dissolved, pour into the carrier, stir gently, make it evenly mixed with the opening agent for nearly ten minutes, then put the starting cup in an oven for 1 hour, take it out and put it in a ten-well container to cool to room temperature. 4.3.4.2 Filling of chromatographic material
Put a small The chromatogram that needs to be dried immediately should be filled with the prepared filling materials in batches, with short intervals between them, and the test should be carried out to the north of the mountain pass. Move the end 4 to the chromatogram outlet, and after a small amount of incineration treatment, connect it to the vacuum system through a rubber tube, open the vacuum system, and continue to fill the material properly, and do not fill it quickly and evenly. After filling, keep it in the inlet for a small amount of time, and keep it properly filled and moved to 4.3.4.3 Aging of the chromatogram
The chromatogram outlet end is connected to the gasification market, and the outlet end is not connected to the detector for the time being. The flow rate is increased by 15mL/in (V) in stages to 4 degrees of aging. |4.3.5~Chromatographic working conditions
