YN-CLVI Pesticide Residue AnalyzerTest Theory
Organophosphate and carbamate pesticide is currently the largest use of pesticides,and more is on the prohibition of the use in fruit,vegetable.This class of pesticides with acetylcholinesterase(Ache) binding in vivo,and are not easily seperated,namely ache activity is inhibited,resulting in the hydrolysis of acetylcholine can't accumulate in nerve conduction,nerve hyperexcitablity symptoms of poisoning and even death.Based on this toxic principle produces enzyme inhibition rate method, the detection principle can be simply expressed as follows: using a sensitive enzyme extract source prepared butyrylcholinesterase as a detection reagent, according to the degree of change in the activity of butyrylcholinesterase fruits and Vegetables samples to determine pesticide residues.
YN-CLVI is the only one instrument which can test heavy metal(Chromium, cadmium, mercury, arsenic and lead) in fruits,vegetabls,food etc.
Main technical parameters :
1.Function:LCD, auto-zero, with high reliability and stability, save data function , English print test results with computer interface (can be used separately without connected to the computer ), to achieve the intelligent management of computer networking.Built homoiothermy incubation tank, automatic temperature control; culture temperature, time, time interval data collection and inhibition rate criteria can be freely set.
2.Wavelength range : 410nm,505nm
3.Inhibition rate measure range : 0~100%
4.Transmittance Accuracy : ≤±0.4%
5.Transmittance repeatability : ≤0.3%
6.Inhibition rate error : ±10%
7.Inhibition repeatability : ≤5%
8.Channel : 6
9.Stability : displayed number(transmittance measurement) drift is less than 0.7 % (A) , within 3 minutes after powering on for 20 minutes
10.Power consumption :≤5W
11.Cultivate heating power : ≤100W
12.Working temperature : Ambient temperature ,Humidity≤ 85%
Testing items :
|1.Heavy metal(Chromium, cadmium, mercury, arsenic and lead) in the food,fruit,vegetable etc.|
|2.Pesticide residue in the food fruit,vegetable etc.|
|3.Nitrate and nitrite in the food fruit,vegetable etc.|
|4.Formaldehyde, sulfoxylate, Sulfur dioxide in food,fruit,vegetable etc|
