Introduce the usage method of portable veterinary drug residue detector
The portable veterinary drug residue detector can quickly detect whether edible agricultural products are safe. The safety of agricultural products containing pesticide residues depends on whether the pesticide residue content in the agricultural products exceeds the standard and whether prohibited pesticides are used. Not all agricultural products containing pesticide residues are unsafe and harmful food. As long as the residue level is below the standard according to the standard requirements, it is safe to eat. Therefore, what we need to judge is whether the pesticide residue content of agricultural products containing pesticide residues exceeds the standard. This detection instrument can accurately determine whether the pesticide residues in agricultural products exceed the standard. The instrument is convenient to detect, easy to operate, portable, and can better meet the pesticide residue detection requirements of different agricultural products.
Usage of portable veterinary drug residue detector:
1. Power on: Press and hold the "on/off" button to turn on the device. After turning on, the instrument will preheat and the bright spot will flash; Press the [Mode] key to switch to "Temperature". When the temperature reaches 40 ℃, the instrument emits a prompt sound, indicating that preheating is complete and testing can begin.
2. Loading: Fold the speed test card along the centerline and unfold it, insert it into the heating plates of each channel under the pressure paper strip, and place the speed test card accurately.
3. Sampling: Select the sample to be tested, wipe off the surface soil, cut it into fragments of about one square centimeter, take 5 grams and put them into a capped bottle, add 10 ml of pure water or buffer solution, shake and let it stand for two minutes, while making a blank control of pure water or buffer solution. Use a pipette to add the sample solution to the white pill for testing.
