📝 Before testing, samples should be returned to room temperature (20–30 °C). For fresh samples, wipe off soil, then cut into fragments smaller than 1 cm in size. Weigh 2.00 ± 0.05 g of sample into a 15 mL centrifuge tube, add 6 mL of extraction solution, cap the tube, vortex or manually shake vigorously for 1 min, and let stand for 5 min to obtain the sample solution. According to the testing requirements, dilute as per the table below to obtain the test solution. | Sample Name | National Standard Limit (mg/kg) | Sample Solution (µL) + Extraction Solution (µL) | |-------------|--------------------------------|------------------------------------------------| | Melon, Wax apple, Lychee, Sweet potato | 0.1 | No dilution needed; use as test solution | | Hawthorn, Plum, Blueberry, Mulberry, Grape, Mango, Strawberry, Garlic, Tomato, Eggplant, Green pepper, Sweet pepper, Spiral pepper, Wrinkled green pepper, Zucchini, Bitter gourd, Cowpea, Kidney bean, Edible-podded pea, Pea, Stem lettuce | 0.2 | 500 + 500 | | Hangzhou pepper, Erjingtiao pepper | 0.2 | 300 + 700 | | Cherry | 0.3 | 335 + 665 | | Kiwifruit, Cauliflower, Celery, Peach, Okra | 0.5 | 200 + 800 | | Lemon, Cabbage, Chinese cabbage, Choy sum, Cucumber | 1 | 100 + 900 | | Kumquat, Chinese kale, Spinach, Bok choy, Romaine lettuce, Stem lettuce leaf, Leaf lettuce | 2 | 50 + 950 | | Amaranth | 5 | 20 + 980 | Note: The table above does not list all measurable samples. For the applicability of samples not listed, please confirm with our Technical Center. This product cannot be used for testing of millet pepper (small chili) and Chinese chives. For sampling methods, refer to the "Administrative Measures for Food Safety Sampling Inspection" (2019 Decree No. 15 of the State Administration for Market Regulation); for national standard limits, refer to GB 2763.

Before testing, samples should be restored to room temperature (20–30°C). Take a fresh sample, wipe off soil, and cut into fragments smaller than 1 cm square. Weigh 2.00 ± 0.05 g of the sample into a 15 mL centrifuge tube, add 6 mL of extraction solution, close the lid, vortex or manually shake up and down for 1 min, and let stand for 5 min to obtain the sample solution. According to test requirements, dilute as per the table below to obtain the test solution. | Sample Name | National Standard Limit (mg/kg) | Sample Solution (µL) + Extraction Solution (µL) | |-------------|--------------------------------|------------------------------------------------| | Melon, Wax apple, Lychee, Sweet potato | 0.1 | No dilution needed; directly used as test solution | | Hawthorn, Plum, Blueberry, Mulberry, Grape, Mango, Strawberry, Garlic, Tomato, Eggplant, Green pepper, Sweet pepper, Snail pepper, Wrinkled green pepper, Zucchini, Bitter gourd, Cowpea, Kidney bean, Edible-podded pea, Pea, Stem lettuce | 0.2 | 500 + 500 | | Hangzhou pepper, Erjingtiao chili | 0.2 | 300 + 700 | | Cherry | 0.3 | 335 + 665 | | Kiwifruit, Cauliflower, Celery, Peach, Okra | 0.5 | 200 + 800 | | Lemon, Cabbage, Chinese cabbage, Choy sum, Cucumber | 1 | 100 + 900 | | Kumquat, Chinese kale, Spinach, Bok choy, Romaine lettuce, Stem lettuce leaves, Leaf lettuce | 2 | 50 + 950 | | Amaranth | 5 | 20 + 980 | Note: The table above does not list all testable samples.

🧪 Test Procedure

before the experiment, Read Before the experiment, please read the instructions carefully. Equilibrate the test cassette, the microwell reagent, and the sample to be tested to room temperature before use. Remove the test cassette from the original packaging bag and use it within 60 min after opening. Mark it and use immediately. After removing the required microwell reagents, immediately close the reagent barrel lid to prevent moisture. Using a micropipette, aspirate 100 µL of the sample to be tested into the microwell reagent, slowly aspirate and dispense (2–3 times) to mix thoroughly with the microwell reagent. Incubate at room temperature for 3 min. Then, using a micropipette, aspirate 100 µL of the mixed solution and add it vertically into the sample well (S well), or use the disposable dropper provided in the kit to slowly add 3 drops vertically into the sample well (S well). Start timing when the liquid flows. React for 10 min, then immediately proceed.
