If the identification method mentioned in door 1 has a time, then it should be at least the same as the external method. 4 3 Determination of carbendazim and thiram content
4.3.1 Method summary
NY618-20D2
The core sample was dissolved in water, propanol and water-ammonia water as mobile phase, and a stainless steel tube and an external detector with a complex phase as filler were used to separate and determine the carbendazim and thiram in the test control by high performance fusion chromatography. The external standard method was used for quantification. 4.3.2 Reagents

Weigh 33 grams of Changshi Nanling standard (accurate three 3.1mg), initial effective ring fence Road benefit (according to the seven confirmed samples of the active ingredients in the sample, accurate to 0.1 in the same: 123ml. Put in a volumetric bottle, 2. Acetic acid: Treat in a ultrasonic disinfector for 10 minutes. After the sample is fully dissolved in a flow cell, add 1 mL of the sample to a volumetric bottle and add 2 mL of the sample. Treat in a ultrasonic disinfector for 1 minute to dissolve all the components. Transfer the sample to a centrifuge and centrifuge for about 200 minutes until the sample is effectively dissolved. NY615--2002 4. 3. 5. 3 Determination
Under the condition of still operation, after the instrument baseline is stable, continuously add the standard solution in the number of needles until the peak of all adjacent needles (Fujian double peak) changes by less than 1.1, and then measure the concentration of the test sample in the order of the concentration of the standard sample. Calculate
the average of the measured values ​​of the two needles of the sample solution and the first two needles of the sample solution are used for the best quality score (the maximum score of the best quality score in the table of good bacteria, Fujian double peak) respectively. Calculation: X
Wherein:
A, the average area of ​​the carbendazim sample in the first standard sample, the liquid density of the four test samples is half of the standard mass of carbendazim (An Xiao), the unit is g (m), the mass of the product is mg/g):
The composition of carbendazim (An Xiao) in the first standard sample, 4.3.7% is allowed as the difference
The total difference between the parallel readings should not be compared. The average value should be taken as the test result. 4. Determination of p value

m1.Put the sample in a three-stage bottle, turn it on, and keep it for 1 minute. Drag it every 15 m. Each time: R, there is no change in its appearance. Under the above conditions, continue to place the bottle in a clean room for 74 minutes, take out the triangle and return to room temperature. Then, perform viscosity and sieve analysis. If the test results meet the standard requirements, they will be qualified. 4.12 Thermal stability test 412.1 In a constant humidity box (at 54°C, only the sealed bottle can still be separated by a 50ml syringe: 50ml. 4.12.2 Test steps: Use a 50ml syringe to inject about 30ml of solution. Test details: Place 3 bottles in a clean bottle (avoid contact with the bottle), seal them with a high temperature seal (avoid volatilization of the agent): weigh them separately, put the sealed bottles in a constant humidity box (or constant temperature water bath) at 54°C for 11 minutes, and then place the bottle in a constant humidity box (or constant temperature water bath) at 54°C for 11 minutes. d Take out, separate the sample of the drug with an area of ​​211 and test the content of the drug, the content of the drug and the rate of registration.
