Embodiment 1
[0025] Such as figure 1 , 2 As shown, the present invention relates to a rapid detection card for pesticide residues, including a front and a back, the front includes a reaction sheet 1, a detection sheet and a quality control sheet, and the reaction sheet 1, the detection sheet and the quality control sheet are connected in sequence, connected Part of it has pressure lines; the back is provided with a reaction sheet 2 on the back of the reaction sheet 1 .
[0026] In this embodiment, both the test piece and the quality control piece are immobilized with acetylcholinesterase, and both the reaction piece 1 and the reaction piece 2 are immobilized with indole acetate.
[0027] In this embodiment, the reaction strip 1 , the reaction strip 2 , the test strip and the quality control strip are folded in half and overlap each other, the reaction strip 1 is in contact with the test strip, and the quality control strip is in contact with the reaction strip 2 .
[0028] In the present...
Embodiment 2
[0036] Example 2 Surface Wiping Method Detects Pesticide Residues in Vegetable without Exceeding the Standard
[0037] (1) Wipe off the soil on the surface of the mustard greens on the market where the pesticides do not exceed the standard, absorb the eluent with a straw, gently add 3 to 4 drops of the eluent on the surface of the vegetable, and then use another piece of vegetable on the drop. Rub lightly.
[0038] (2) Take a quick test card, and drop all the liquid on the vegetables on the white "detection piece" of the quick test card.
[0039] (3) Use a pipette to gently add 2 drops of clean eluent to the white "quality control sheet" on the quick test card.
[0040] (4) First, fold the fold line between the "test piece" and "reaction piece 1" in half so that the white "test piece" is in contact with the red "reaction piece 1", and then put the "quality control piece" and the "reaction piece" together. Fold the half-fold line between sheet 2" in half again, so that the "q...
Embodiment 3
[0044] Example 3 The overall test method detects pesticide residues in vegetables that do not exceed the standard
[0045] (1) Wipe off the soil on the surface of the mustard greens that do not exceed the standard of pesticides on the market, and tear the vegetables by hand or use scissors to cut the vegetables into leaves about 1×1cm in size. Add 20 vegetable leaves to the washing bottle, add 2ml eluent with a straw, shake gently 50 times and wait for 2 minutes.
[0046] (2) Take a piece of quick test card, gently drop 2 drops of clean eluent onto the white "quality control piece" on the quick test card with a straw.
[0047] (3) Use a dropper to absorb the vegetable soaking liquid in the washing bottle, and gently drop 2 drops on the white "test sheet" of the quick test card.
[0048] (4) First, fold the half-fold line between the test piece and the reaction piece 1 in half, so that the test piece is in contact with the reaction piece 1, and then fold the half-fold line bet...
