Preparation of standard solution

Weigh azoxystrobin standard 0.05g (accurate to 0.0002g), Ge in 50ml volumetric flask, dissolved in acetonitrile and dilute to volume, and mix. Pipette accurately pipette the solution 5ml to 50ml volumetric flask another dissolved with acetonitrile and diluted to the mark, mix and set aside.

Preparation of the sample solution

Weigh containing azoxystrobin about 0.05g (accurate to 0.0002g) sample, Ge in 50ml volumetric flask, diluted to explain the compatibility with the flow volume, and mix. Transferred to a centrifuge tube, centrifuged, the supernatant was filtered membrane filtration. Pipette accurately filtrate 5ml pipette to another 50ml volumetric flask, dilute to the mark with acetonitrile dissolved, mix, test.

Determine

Under these operating conditions, after the instrument baseline stable, continuous injection of several doses of the standard solution (less than 5-pin), calculate the relative response of repetitive needle until two adjacent needle relative response time of less than 1.5% change , according to the solution, the sample solution, the sample solution, standard sequence of the standard solution is measured.
