Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

1. portable ultraviolet lamp analyzer overview:

Portable ultraviolet analyzer is one of the series of instruments newly developed by our company. It adopts imported components and high-intensity ultraviolet lamps. It has the advantages of small size, light weight, high ultraviolet strength and convenient use. Due to the use of 365nm and 254nm wavelength ultraviolet rays, which have been widely used in the world, the sensitivity is higher and the damage to the sample is small. Its UV intensity reaches the level of similar products for import and export, and it is one of the necessary instruments for PCR technology (gene amplification technology). It is widely used in molecular genetics, molecular biology, biochemistry, medical examination, biological products and other fields.

2. portable ultraviolet lamp analyzer uses:

1. In scientific experiments, it is a necessary instrument for detecting many major substances such as proteins, nucleotides, etc. It can be used for observation, analysis and photography of DNA RNA electrophoresis gel samples.

2. In production and research, it can be used to check the quality of various fluorescent drugs such as microbial alkalis and vitamins. It is especially suitable for thin layer analysis, paper layer analysis spots and detection.

3, in the dye coating rubber, petroleum and other chemical industries, the determination of various fluorescent materials, fluorescent indicators and additives, different types of crude oil and rubber products.

4, in the textile chemical fiber can be used to determine different types of raw materials such as wool silk man-made fibers, cotton, synthetic fibers and can check the quality of finished products.

5. In the grain and oil, vegetable and food departments, it can be used to check the quality of food additives, spoiled vegetables, fruits, chocolate, fat, bee room, sugar, eggs, etc.

6, can also be used for public security departments to prove identification.
