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.

Product features:

ZF-1Ultraviolet analyzerIt is composed of ZSZ-6-A and ZSZ-6-B ultraviolet lamp tubes and filters. The ZSZ-6-A emits (short wave 254-mm wavelength, ZSZ-6-B (long wave) 365-nm wavelength, one machine can also emit at the same time, mixing two wavelengths. The machine has low power consumption and low heat, and can be used continuously for a long time. The biggest advantage is that it can be used with opening and closing, which is very convenient. The light emitted by the ultraviolet lamp tube is filtered by a filter to remove visible light, thus providing intense 254nm and 365nm ultraviolet light for fluorescence analysis.

Product use:

(1) In scientific experiments, many major substances such as proteins, nucleotides, etc. are detected.
⑵ In drug production and research, it can be used to check hormone alkaloids, vitamins and other energy. The quality of fluorescent drugs is produced, which is especially suitable for thin-layer analysis and 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, identification of different types of crude oil and rubber products.
Textile chemical fibers can be measured in different types of raw materials. Such as wool, silk man-made fibers, cotton, synthetic fibers, and can check the quality of finished products.

In the grain and oil, vegetables, food sector, can be used to check the toxin. Food additives, the quality of spoiled vegetables, fruits, cocoa beans, chocolate, fat, honey, sugar eggs, etc.
In geology, archaeology and other departments, can play a variety of minerals found, distinguish the authenticity of cultural relics fossils.
(7) In the * * department can check the finger marks to determine the secret writing, etc.
