Isoprocarb Residue Detection Test Card
This kit is suitable for qualitative detection of residual isoprocarb in fresh cucumber sample.
Isoprocarb is a touch-and-kill, quick-acting pesticide, which is a highly toxic pesticide. It is mainly used to control rice planthopper, rice cicada and other pests on rice, some fruit trees and crops. Toxic for bees and fish.
High performance liquid chromatography-tandem mass spectrometry was used for residue determination because of high selectivity and simple treatment. Compared with HPLC methods, our kit show considerable advantages regarding sensitivity, detection limit, technical equipment and time requirement.
(1) Before testing, the samples should be restored to room temperature (20-30℃).
Fresh samples should be taken to wipe away the soil and cut into pieces less than 1cm square.
(2) Weigh 1.00± 0.05g sample into 15mL polystyrene centrifuge tube, then add 8mL extract, close the lid, oscillate up and down manually for 30s, and let it stand for 1min. Supernatant liquid is the sample to be tested.
Note: The sampling method refers to the food safety sampling inspection administration measures (aqsiq decree no. 15 of 2019). GB2763 2019 for reference.
Negative(-) : Line T and Line C are both red, color of Line T is deeper than or similar to Line C, indicating the isoprocarb in sample is less than LOD of the kit.
Positive(+) : Line C is red, color of line T is weaker than line C, indicating isoprocarbl in sample is higher than LOD of the kit.
Invalid: Line C has no color, which indicates the strips are invalid. In this case, please read the instructions again, and redo the assay with new strip.
Save the kits in a dry environment of 2 ~ 30℃ away from light.
The kits will be valid in 12 months.
