Pesticide Residue Rapid Detection Reagent (500)

Pesticide Residue Rapid Detection Reagent (500) is designed for the detection of pesticide residue in vegetables.

Pesticide Residue Rapid Detection Reagent (500) is designed for the detection of pesticide residue in vegetables. This reagent has the characteristic of well stability and high sensitivity, and could be used on various types of pesticide detecting instrument.

1, Pesticide residue test reagent include 10 packages of buffer powder, 10 bottles of cholinesterase, 2 bottles of Chromogenic reagent, and 4 bottles of substrates. All these item could offer 500 times detection.
2, When using any reagent, please exhaust the open one before reopening a new one in case they go bad.
3, Biochemical reaction will occur immediately when enzyme, substrate and chromogenic reagent meet together. So pipette and container should be labeled ,used alone in order to avoid cross-contamination .
4, When sucking the reagent from the bottle, it is strictly forbidden to inject the reagent back to the bottle.
5, Control the speed of action during using pipettor to suck reagent or drop reagent , in case the quantity of reagent is not accurate. Besides, it is helpful to protect the pipettor.
6, Inhibition rate could be calculated by formula: [( ΔΑ 0 －ΔΑ t )/ ΔΑ 0 ]×100%;
7, Normally, Inhibition rate could be calculated by pesticide detecting instrument automatically,
8, Inhibition rate≥50%: Positive result, it is recommended to detect again with gas chromatography.
9, Inhibition rate≤50%: Negative result.

This kind of pesticide residue rapid test reagent is very stable, and it can be transported in room temperature. For long term storage, it should be stored at 4 ℃, and the expiration time is 12 months. If it is stored in room temperature or normal temperature, the expiration time is 3-6 months.

Pesticide of organophosphorus and carbamate could inhibit the activity of cholinesterase under certain conditions. Whether the samples contain organophosphorus or carbamate could be determined through the calculation of inhibition rate, which has positive correlation with pesticide concentration .

Rapid Detection

Pesticide Residue Rapid Detection Reagent (500) can be used in various types of pesticide detecting instrument and spectrophotometer.
