Product introduction:

1. It is used for the detection of organophosphorus and carbamate pesticide residues in agricultural products such as fruits and vegetables. The detection adopts the enzyme inhibition rate method in the national standard, which is a relatively sensitive, efficient and accurate rapid detection method for pesticide residues in China.

2. The automatic pesticide residue detector realizes the full automation of rapid detection of pesticide residues. It has built-in detection reagents such as enzymes, substrates, and chromogenic reagents. During detection, only the sample to be tested needs to be put in, and reagent addition, mixing and warm bathing are automatically completed. , which can achieve accurate and rapid detection of pesticide residues. During the detection process, the temperature is constant, the reagents are quantitative, and the detection process and use can be automatically cleaned, which is simple, fast, stable and reliable, and eliminates the errors introduced by human factors in traditional detection.

Summary of advantages:

1. Easy to operate: The whole machine is designed in an integrated manner, with an integrated main control system, human-computer interaction system, and a miniature thermal printer. The stand-alone full-featured independent operation does not require other peripherals.

2.Technical advantages: The patented “a quantitative liquid addition device” patent (patent number ZL 2017 2 1371384.3) is used for sample addition and mixing technology, multiple reagents are added independently, and the sample addition needle has no contact with the sample during the whole process, which completely eliminates the sample Cross contamination possible.

3. Environmental protection: There is no need to clean the pipeline and sample needle in the whole process of detection, no cleaning liquid and no waste liquid are generated, and the detection process is more environmentally friendly.

4. Fully closed-loop control: Built-in multiple sensors, automatically identify the presence or absence of samples, high-precision closed-loop temperature control, precise dropwise addition of reaction reagents, and timely feedback of reagent inventory.

5. High detection accuracy: a single-wavelength interference filter is used to eliminate the influence of spectral drift of the light source; the reference channel signal is detected synchronously, the fluctuation of the light source is automatically corrected, and the self-developed signal detection algorithm is adopted, which greatly improves the detection accuracy of the instrument.
