Today, as food safety is increasingly valued, pesticide residue detectors are one of the important technical equipment to ensure the quality and safety of agricultural products. Pesticide residue detectors are professional detection equipment based on the principle of enzyme inhibition rate colorimetry. They can quickly and accurately detect organophosphorus and carbamate pesticide residues in food, safeguarding the entire chain of food safety from farmland to table.

The pesticide residue detector uses the acetylcholinesterase inhibition method, and the core detection process is as follows:

Sample extraction: Take 2g of food sample, add 10mL buffer and shake for 2 minutes

Enzyme reaction: Add acetylcholinesterase reagent and react at 37℃ for 10 minutes

Optical signal detection: Measure the absorbance change of the reaction solution through an imported LED light source (wavelength 412nm)

Intelligent judgment: Inhibition rate ≥50% is automatically judged as positive, and the instrument generates a test report simultaneously

This technology complies with the national standard GB/T5009.199-2003, and the detection limit for organophosphorus (such as dichlorvos) and carbamate (such as carbaryl) pesticides is 0.01mg/kg.

Functional analysis of pesticide residue detector:

1. Multi-channel efficient detection

16 independent detection channels, support cycle detection, 16 samples can be analyzed in 15 minutes

Channels do not interfere with each other to ensure data accuracy

2. Intelligent operation experience

7-inch touch screen guided operation, non-professionals can master it in 10 minutes

Built-in 100+ food database, support custom addition of new varieties

Automatically print test reports, including key information such as tester, time, and location

3. Environmental adaptability

Imported LED light source has intelligent constant current voltage stabilization function, long-term work without temperature drift

The colorimetric cell is equipped with a temperature control module (±0.1℃ accuracy) to eliminate environmental interference

4. Data interconnection capability

Support WiFi/4G dual-mode transmission, and test data is uploaded to the supervision platform in real time

Historical data is traceable and supports big data statistical analysis

The emergence of pesticide residue detectors has made the detection of pesticide residues in food more efficient, convenient and reliable. Its fast and accurate detection capabilities provide strong support for the construction of a complete food safety guarantee system, and are becoming an important technical equipment to protect the "safety on the tip of the tongue" of the people.
