The other three items are mentioned in the table
pH value range
(reversePlace the sample in a 100ml volumetric flask, add 90ml methanol, and sonicate in an ultrapure disinfector for 10min until the effective components are fully eliminated. Take out the effective oxygen and adjust the volume with methanol and mix well. NY6222002
Gradually transfer part of it to a 1ml centrifuge tube and centrifuge it at a speed of 2/min to the standby standard sample and sample. The amount can be appropriately adjusted to make the effective content of the standard sample and the test solution equal. 4.3.5.3 Determination
Under the above working conditions, wait for the instrument to move linearly and continue to concentrate the standard sample. When the peak area between the first and second needles is less than 1.5%, the determination is carried out in the order of standard solution, test solution, test solution, and standard solution. 4.3.6 Calculation
Average the peak areas of methyl sulfophos (methamidophos) in the thin needle sample solution and the standard sample solution before and after filtration of the sample, and calculate the content of methyl sulfophos (methamidophos) in the standard sample expressed as a cut-off fraction X (%) according to formula (1): X,=xixP
