What Are the Main Tests of Pesticide Residue Speed Measurement Instruments? How to Detect?

  Author:MeCan Medical–ultrasound machine manufacturers

What are the main tests of pesticide residue speed measurement instruments? The role of pesticide in agricultural production is inseparable from the role of pesticides. The application of pesticides has a certain guarantee for the yield and quality of crops, and prevents the invasion of diseases and diseases. At present, the production of agricultural production is inseparable from the use of pesticides. The pesticide types commonly used on the market are organic phosphorus and amino -based pesticides. kind.

The pesticide itself has a certain toxic effect, and a large number of pesticides can cause serious pesticide residues. These pesticide residues are attached to crops and entered the human body to harm the health and safety of the human body through the food chain. Therefore Speaking is a very important content.

However, pesticides are a substance that cannot be distinguished by the eyes, so we need to use pesticide residue speed measurement instruments to measure pesticide residues on agricultural products, and to show us in the form of data, intuitively understand the quality and safety of agricultural products, facilitate production personnel and production personnel and Sales staff take timely measures to reduce the risk of agricultural product safety accidents.

How to detect pesticide residue speed tests? Let's take a look at the detection method.

1. Pour the buffer reagent bag reagent, dissolve in 500ml distilled water, and dissolve and mix well.

2. Add 10ml distilled water to the bottle labeled as a substrate.

3. Add 10ml buffer to the bottle marked as a color renderendant and enzyme reagent, respectively.

4. Put 2G samples in the sample cup, add 10ml buffer to extract for 2 minutes, the filter liquid is the sample extraction solution

5. Take the corresponding liquid into the test tube, shake the test tube for about 5 times, pour it into the container, put the containment dish in the specified channel, one channel is the control solution, and the second channel is the sample solution

6. The on -board operation adjusts the response time to 180 seconds. Click to detect. The sample suppression rate is less than 50%.

The main role of pesticide residue speed testing instruments in the market is preliminary testing and screening of quality and safety of agricultural products such as vegetables, which is an important barrier to ensure the safety of vegetables. Because of its small size and convenient carriers, it can be used in various occasions, which effectively ensures that agricultural products meet the prescribed quality and safety standards, ensure their benefits, and also make consumers feel more assured.

What Are the Detection Methods for Fully Automated Biochemical Analyzers? Take a Look
  Author:MeCan Medical–ultrasound machine manufacturersBiochemical analyzers can be divided into fully automatic instruments and semi -automatic instruments. Among them, semi -automatic instruments are small, simple structure, and cheap in the current market. The error is small, and this type of instrument usually has an automatic reporting abnormality and can automatically correct the working state, so the system error is small. With the rapid development of my country's medical industry, pathological diagnosis has gradually developed in the direction, the market demand for fully automated biochemical analyzers has continued to rise, and the industry has more development potential. So, what are the detection methods for fully automated biochemical analyzers? In response to this problem, people who may not understand are unclear, and follow the editor of Prank Medical Equipment.1. Transparent than turbidity. Measure the transmission intensity to the incident light intensity ratio in the direction of the light source, and determine the solution of the suspension or the grade in the collagen solution through this ratio, which is called the transparent ratio method.2. Ending method. After a period of reaction (usually 10 minutes), the entire reaction reaches a balance. All the measured objects have transformed into a product. The concentration of the measurement is proportional.3. Fixed time method. It means that within a certain response time, the reaction speed is proportional to the one of the concentration of the reactor. Because the reaction is constantly consumption, the overall reaction speed is constantly decreasing, which is more likely to increase (or decreases) the speed of the light absorption (or decreases). The smaller, because the reaction reaches a long period of time, it must be monitored within a certain period of time.4. Fasics method. Refers to the continuous measurement (monitoring every 15 seconds to 1 minute). In the process of the reaction of the measured object, the concentration of a reaction product or substrate changes over time to find the initial speed of the measurement reaction, that is, the continuous monitoring method Essence5. Reflective optical method. Fix the part or or all reagents required for the reaction in advance in a carrier with a special structure, add the liquid sample to the carrier, and the chemical color reaction of the reagent in the carrier and the reagent in the carrier, through visual definition or semi -definitation, or or semi -definitation, or or the semi -fixed nature, or or the semi -fixed nature, or or the semi -fixed nature, or or Change the signal of the signal on the carrier of the instrument.The above briefly introduces the detection method of fully automated biochemical analyzer. In fact, with the expansion of the clinical application range of the fully automated biochemical analyzer, its performance advantages are becoming more and more obvious. The fully automated biochemical analyzer is an instrument in the liquid to analyze a specific chemical component in the liquid. Due to the advantages of fast analysis, high analysis speed, high accuracy, and small consumption dosage, etc., it has been applied to the fields of epidemic prevention stations, hospitals, family planning service stations, etc. For testing and analyzing life chemicals. The diagnosis and treatment of Chinese diseases provide information basis. If you want to know more about the product knowledge of more automated biochemical analyzers, you can consult: 400-6656-888.
