China Education Equipment Purchasing Network News: Some vegetables with multiple pesticides have passed through the pesticide residue testing of multiple circulation links and the "green light" has caused many people to worry about the vegetables on their tables. The reporter consulted the Western Xinqiao Agricultural Products Logistics Center with a daily trading volume of 6,000 tons and 60% -80% of the consumption of vegetables by the citizens of Xi'an. Fine inspection again. To enter the market and sell, "abnormal pesticide residues" absolutely do not think about it.
Quick door inspection: at least 100 batches are inspected every day
"There are trucks entering the market 24 hours at any time, and we will check the dishes before the vehicles come in." The staff of Xinqiao Market Quality Inspection Center said that there are about 50 or 60 kinds of vegetables sold in the market. The quality inspection center guarantees at least every day. Sampling 100 batches, "If there is a peak period, we will follow the vehicle to open the position first, and then immediately check."
After passing the random inspection, the market will issue a "dishes, origin, qualified" brand to the vegetable merchants, and the rest of the merchants who come to buy can also see it at a glance. "Only the certificate of exemption issued by the place of origin can be exempted." The staff of the Quality Inspection Center said that the center has more than 20 professionals on duty 24 hours a day. Among them, the staff of the Municipal Agricultural Inspection Center and Yanta District Agricultural Inspection come as supervision departments. Assist and supervise the random inspection.
Precision instruments: can detect more than 50 kinds of pesticides
It is understood that the quality inspection center of Xinqiao Market has a total of 6 inspection chambers including "gas phase chamber, liquid phase chamber, atomic absorption chamber, organic pretreatment, inorganic pretreatment, and rapid measurement chamber". Dishes should be quickly tested before entering the market To conduct a comprehensive pesticide residue evaluation, once the comprehensive index exceeds the standard, it will be sent to the remaining 5 testing rooms for specific "over-standard types and amounts" analysis. "The five test chambers can detect more than 50 pesticide residues in total, and the atomic absorption chamber also specifically introduces advanced foreign equipment to measure heavy metal elements in agricultural products and their environment." The staff introduced step by step.
NYW1008 pesticide residue detector
Instrument introduction:
This instrument strictly follows the provisions in the "Quick Detection Method for Organophosphorus and Carbamate Pesticide Residues in Vegetables" for the rapid determination of organophosphorus and carbamate pesticide residues in vegetables. It is an upgraded product of the first generation pesticide residue detector in China,
The detection is more accurate, and the 10-channel independent light source detection solves the time error caused by the first generation of pesticide residue detectors, where multiple channels share the same light source
The function is more powerful, which effectively solves the problems of future upgrades and additions of other testing items. The instrument reserves other testing programs and ports, and can easily add testing items independently according to future needs.
Stronger environmental adaptability Built-in high-capacity battery, can stand by for more than 6 hours, and can be equipped with car inverter power supply, can work in the field, in the car, power outages in various complex environments
The printing result is richer. The instrument can print the Chinese product name, which solves the defect that the first generation instrument can only print the code, and can automatically judge whether the test result is qualified, instead of human judgment, making the test result more intuitive
Detection principle: Under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively related to the concentration of the pesticide. Under normal circumstances, the enzyme catalyzes the hydrolysis of a neurotransmitter metabolite (acetylcholine), and the hydrolysate developer reacts to produce a yellow substance. The pesticide residue detection instrument measures the change in absorbance with time, calculates the inhibition rate, and can be judged by the inhibition rate Check whether the sample contains organophosphorus or carbamate pesticides.
The main technical indicators of the instrument:
1. Photocurrent stability: ≤ ± 1% T / 3 minutes
2. Transmittance accuracy: ≤ ± 1.5% minutes
3. Transmittance repeatability: ≤0.5%
4. Inhibition rate display range: 0 ～ 100%
5. Absorbance display value range 0.001-4.000
5. 10-channel independent light source detection, free to choose the use channel, can measure 10 samples at the same time
6. Test time: 1-9 minutes optional
7. 110mm × 64mm LCD color display, the test results are automatically printed and 4,500 test data are automatically saved
Features:
â— Strictly in accordance with national standards: suitable for rapid determination of organophosphorus and carbamate pesticide residues in vegetables
â— The upgrade program is reserved, and it can be upgraded to a comprehensive instrument for testing, aquatic products, meat products, and noodle products in the future.
â— Convenient operation: LCD large screen, Chinese prompt operation can be operated without professionals
â— The instrument can set the information of the purchase unit according to customer requirements, and can be printed on the test report, which can better reflect the authority of the test results and facilitate publicity (unique in China)
â— Enhanced environment adaptability Built-in high-capacity battery, can stand by for more than 6 hours, and can be equipped with car inverter power supply, can work in the field, in the car, power outages in various complex environments
â— More than 24 vegetable names can be set, and can be adjusted according to customer requirements
â— The test report can print the vegetable name, inhibition rate, whether it is qualified, test date, test unit (all in Chinese, (unique in China)
â— The instrument can be set to use channels to effectively avoid mutual interference between channels and affect the test results (unique in China)
â— Control and sample detection at the same time: 10 samples can be tested in the fastest one minute
â— The instrument automatically judges whether the test data is qualified, instead of manual judgment, the test result is more intuitive
â— Advanced expansibility: both microcomputer control and instrument independent detection are available, and the operation is more flexible
â— The instrument can store test data and query at any time. The saved information includes, sample name (Chinese), test time, test personnel, test data, result judgment and other detailed data (the most complete in China)
â— The instrument is equipped with a brand-name thermal printer, which can print the test results at any time, without changing the ribbon for life, and the printing speed is 6 times that of ordinary printers
â— Low failure rate: the light source is self-checked when the instrument is turned on, and there is no need to manually adjust the light block of the same type of domestic instrument, that is, there is no future maintenance, and the light source is more accurate
â— The instrument performs the self-checking of the light source's effectiveness every time after the test is completed, without manual adjustment with light block
If the pesticide residues are found to exceed the standard, the market will not only prevent the batch of vegetables from entering, but also report to the relevant government departments as soon as possible.
Xinqiao Market: Very few vegetables with excessive pesticide residues
At present, the sales volume of Xixinqiao Agricultural Product Logistics Center with a daily transaction volume of 6,000 tons radiates the five northwestern provinces, and it is also the source of some large vegetable wholesale markets in Xi'an, which can basically meet 60% -80% of the consumption of vegetables by Xi'an citizens.
"In recent months, our quick inspections have been 100% Lily." The staff of the market quality inspection center said that the situation of dishes with excessive pesticide residues was found to be very small. The market promised not to allow vegetables with excessive pesticide residues to enter the sales link, but also food for ordinary people. Add an extra layer of security.
