Cooperative content The sampling capacity of the two products should be about 150 ml. The maximum sampling volume should be not less than ml. 4.2 Identification test The high-efficiency chromatographic method was used to determine the content of carbendazim and Beijing Baicao. Under the corresponding chromatographic conditions, the retention time of carbendazim in Jiangluowan Zhongrong Baicuolan was within 1/2 of the retention time of the standard solution. When the identification method mentioned above is ineffective, at least one other method should be used for identification. 4. 3 Determination of carbendazim and chlorpyrifos content
4.3.1 Method
NY620—2002
The test rod is dissolved with methanol, and isocyanate-ammonia water is used as the mobile phase. The stationary phase is used as the filling material and the external detector. The carbendazim and chlorpyrifos in the test are measured by reverse HPLC and quantified by external standard method. 4.3.2 Reagents

use the juice to shoot and leave about m test selection, juice people clean the new test to avoid touching the bottle level piece high temperature fire box (break to avoid dropping the agent to dismantle the hair). At least, respectively allowed to record. The good security class 1 enterprise belongs to the wear, the group will be in 51 to 2 (nine boxes (constant temperature water answer) can be taken on the 11th, the security book will be frozen before the quality of the soil change test, within 124h, for more than times. The white content of the benefit base floating thing to achieve the effect. Standard test drilling The decomposition rate of the polyol and polyol containing 100 grams of chlorpyrifos is less than 5%, and the toxicity rate is judged as the intermediate standard.
4.13 Inspection and acceptance of products
The inspection and acceptance of products shall contain the relevant provisions of the G certificate of 50. The maximum effective treatment is about 100%, and the household modification method is about 50%. 5 Marking, labeling, packaging, storage and transportation
5.1 The polyol base rate of the coating shall be in accordance with the relevant provisions of T3795. 5.> Polyol base rate of the coating shall be packaged as 0k, 2g, Wkg, and can be selected according to the use : To obtain or loan the European system to ask for the type of packaging, the fee is funny to check the requirements. 5.3 The packaging should be stored in a dry warehouse. Avoid moisture and exposure during transportation. 5.5 In the instruction manual or packaging, there should be toxicity, symptoms, and emergency measures in addition to the relevant labels.
