For a series of aquatic product quality and safety incidents in recent years, such as the detection of malachite green in exported eel products and nitrofuran in Duobao fish, Blue Rainbow Technology, as a professional and comprehensive company specializing in scientific instruments and inspection and testing, has always actively responded to market hotspots and emergencies, and quickly launched a series of solutions.

1Quinolone detection systemApplication scope:

Suitable for qualitative and quantitative detection of malachite green, furazolidone (AOZ), furantadone (AMOZ), nitrofuran (AHD), furacilin (SEM), chloramphenicol, sulfonamides, quinolones, enrofloxacin and other aquatic products such as fish and shrimp.

2、 Product Overview:

The use of immunochromatographic technology to qualitatively detect chloramphenicol residues in samples such as fish, shrimp, chicken, pigs, and cattle has the characteristics of simple operation, short detection time, and direct visual interpretation of results. It is suitable for rapid on-site detection in various enterprises and testing institutions.

3、 Product performance:

1. The Android intelligent operating system adopts more efficient and user-friendly operation. The instrument has Ethernet connection, WiFi network upload, GPRS wireless remote transmission function, and can quickly upload data.
2. High degree of intelligence, the instrument has self checking function: it has power on self checking and zero adjustment functions, and automatic detection of repeatability function.
3. The new generation of high-speed thermal printers can automatically print inspection reports and QR codes upon completion of testing.
4. The instrument is equipped with a regulatory platform. The data can be uploaded via LAN and Internet, and the test results can be directly transmitted to the food safety supervision platform. Conduct regional food safety supervision, big data analysis and processing, and data statistics, detect the long-term and short-term dynamics of regional food safety, and achieve food safety problem estimation and early warning.
6. Integrated portable rapid testing equipment, meeting the needs of on-site and mobile testing, capable of detecting all testing items under the same software, and displaying testing results intuitively through the same window.
7. Colloidal gold module detection method: track type automatic transmission scanning, automatically exits the detection card after the detection is completed.
8. CT line automatic recognition, no need for manual adjustment.
9. The instrument has a multi category sample menu library, which allows for flexible selection of detection samples. Different detection channels can simultaneously detect different sample items.
10. Sample processing is simple and labor-saving, and the overall operation is fast, safe, and convenient.
11. The instrument has its own protection function, which can set a username and password to prevent non staff operations.
12. High sensitivity, high detection accuracy, high repeatability accuracy, scanning high-precision optical sensor.
13. Built in powerful database allows for direct selection of sample names, detection indicators, and inspection units on the instrument, as well as direct editing and input of sample names, detection indicators, inspection units, and other information into the sample database.
14. The instrument has the functions of recalibration, locking, and factory reset.
15. Supports USB storage. The result judgment line can be modified, the reference value calibration value can be saved, and data will not be lost when power is turned off.
16. Compatible with all colloidal gold cards on the market, with unrestricted use of consumables, greatly enhancing the user experience.

Instructions for using colloidal gold cards:

Sample Processing

1. Take over 100g of representative sample and crush it. Weigh 3.0g of evenly crushed sample and add it to a 15mL centrifuge tube.

2. Accurately add 5mL of reagent A to a 15mL centrifuge tube, seal the bottle cap tightly, and mix the sample up and down for 3 minutes.

3. Centrifuge the above sample at 4000rpm for 3 minutes, take 3mL of supernatant and transfer it to a 10mL centrifuge tube. Blow dry it under nitrogen (air) in a water bath at 50-60 ℃.

4. Add 0.5mL of reagent B and 0.3mL of diluent, mix well, let it stand until the liquid is clearly stratified (or centrifuge at 4000rpm for 3 minutes), and test the lower layer of liquid.

[Testing steps]

1. Before use, restore the detection card and the sample solution to room temperature, remove the detection card from the packaging bag, and lay it flat.

2. Add 5 drops of the test solution into the sample well using a disposable dropper.

3. After adding the sample, start timing and observe the results within 5-8 minutes. After 8 minutes, the interpretation is invalid.

4. After adding the sample, start timing. Within 5-8 minutes, operate the machine to pop up the slide, insert the colloidal gold card to read the values, record the results, and print out the test report

Attention: The dropper used for adding samples must be disposable to prevent cross contamination.

In the detection of illegal added substances in aquatic products and products, nitrofuran drugs, malachite green fungicides, as well as antibiotics such as chloramphenicol, fluoroquinolones, and sulfonamides, are worth special attention and are common detection items.
