Chapter 3 of this standard and Chapter 5 are mandatory, and the rest are recommended. This standard is a revision of the chemical industry standard 1JG3292198S grass rubber emulsion. The main differences between this standard and G32921939 are: the addition of a new standard, the content index of butachlor is adjusted to 6%-50% and 50% respectively, and the pH range is adjusted from 5% to 5.0~8.0. The provision of the protection of the content of benzylamine within the warranty period is added: the allowable increase rate of water content within the warranty period is added. This standard will be implemented from the month and replace H322-18.

The general idea is that under normal conditions, the test should be conducted at least once a month. Test method
4.1 Sampling
50% EC
The sampling method was carried out according to the sample size of the sample prepared by the analytical fluid in 13633-7!985. The sampling amount was determined by the random number table method, and the total sampling volume should be no less than 200m1. 4.2 Identification test
4.2.1 Gas chromatography. This identification test can be carried out at the same time as the determination of the content by the single method. Under the same chromatographic detection conditions, the retention time of the sample peak and the retention time of the standard butachlor should have a relative difference within 1%. 4.2.2 Liquid chromatography: This experiment used Cu2+, CH2O3:H2O4=70:50 pH=3 as the mobile phase, and under the same detection wavelength of 2251 nm, the retention time of a peak in the sample and the retention time of the butachlor peak in the standard should have a relative difference within 1.3%. 4.3 Determination of butachlor content
4.3.1 Methods: The sample was dissolved in a methane flask with phosphorus barrier as internal standard. Using 5-sF-3n/(lmmsrlW4T>MCS<180.-253m? as filler, the butachlor in the sample was separated by gas chromatography. 4.3.2 Preparation and method: Trimethane.

Accurately weigh 2mT of SF-fixative solution. Add appropriate amount of alkyl slightly larger than the carrier volume to make it completely lubricated, slowly add 9.56% of the carrier, gently stir to mix evenly and evaporate the agent, then put the beaker into a 12℃ oven for 1-11 minutes. Collect and place in a desiccator to cool to 4.3.4.2 Filling of color inspection
Put a small bucket according to the outlet of the selected process, fill it with the prepared flash filling in batches, and keep lightly covering it until it reaches 1.5m away from the entrance. Move the bucket to the entrance of the color grinding column, plug a small hole at the end of the end of the alkylation, connect it to the vacuum pump through a rubber ring, turn on the pump, and continue to add slowly Filling material: and keep gently pressing it to make the filling evenly condense. After filling, put a small ball of cotton wool at the inlet end and press it down to prevent the filling material from moving. 4.3.4.3 Standardization of chromatographic column
Connect the inlet of the Xeno column to the vaporization chamber. The outlet end is not connected to the detector for the time being, and pass the carrier gas (N2O3) at a flow rate of 15ml./m1:n, the temperature of the separation section is 26, and the aging is carried out here for 48h

Soft take "biamine standard sample 0.1g fine grinding to 0.0302), stomach.- Add 5 mL of internal standard solution to the vial using a pipette:
4.3.6.2 Preparation of test solution
Weigh approximately 0.1 g of the sample containing butadiene rubber to an accuracy of 0.3) Place in a required volume and pipette the same filter tube used in 4.3.6.1 to accurately add 5 mL of internal standard solution and extract. 4.3.6. 3 Determination
Under the above operating conditions, after the instrument is stable, the number of injections is continuously increased, and the change of the relative response value of each injection is calculated. When the relative response value of two adjacent injections of butachlor changes less than 1, the determination is carried out in the order of standard sample drop, sample drop, sample drop, and standard sample drop. The ratios of the peak areas of butachlor to the internal standard in the two sample solutions and the two standard samples before and after are averaged and calculated to obtain the mass fraction of butachlor in the column (%), according to formula (1), X, = mP
where m is the average peak area ratio of butachlor to the internal standard in the standard sample drop, m is the average peak area ratio of butachlor to the internal standard in the sample drop, m is the mass of the standard sample,
