6 measuring step
6.1 Direct weighing method
6.1.1 Sample preparation solution
Weigh thiamethoxam standards about 0.02g (accurate to 0.00002g), placed in 100mL flask with 5mL water and 50mL acetic
Nitrile (4.1) to dissolve the sample, and then as a diluent with acetonitrile (4.1), dilute to the mark, in an ultrasonic bath for about 5min ultrasound shake. That
Standard working solution, placed in the 0 ℃ ~ 5 ℃ refrigerator spare, valid for six months.
NOTE. The standard weighing range. 0.01g ~ 0.06g.
