Application of UV-Vis Spectrophotometer UV-1800 in Life Science

Key words: UV-visible spectrophotometer; life science; aesthetic instrument ; UV-1100; UV-1800

At present, the application of UV-visible spectrophotometer is mainly in quantitative analysis. First introduced from the application of life sciences. UV-visible spectrophotometers are widely used in life sciences. The most important are the following five aspects. 1. Application in protein analysis work UV-visible spectrophotometer in the analysis of proteins, the most important is the detection of protein content; generally in the absorption peak of protein as absorbance determination. Because the main absorption wavelength of the protein to ultraviolet light is 280 nm, the photometric measurement mode is adopted, and the wavelength GOTO of the instrument is applied to the maximum absorption peak wavelength of the protein of 280 nm, and the absorbance is tested to complete the quantitative detection of the protein. 2. Application in Nucleic Acid Analysis The application of UV-Vis spectrophotometer in nucleic acid analysis is mainly used for quantitative detection of nucleic acids; because the absorption peak of nucleic acid is 260 nm. We only need to use the photometric measurement mode to measure the absorbance of the wavelength of the ultraviolet-visible spectrophotometer GOTO to the maximum absorption peak of the nucleic acid of 260 nm. 3. Application in Amino Acid Analysis The application of UV-Vis spectrophotometer in amino acid analysis is mainly used for the quantitative detection of amino acids. Because the main absorption wavelength of amino acid to ultraviolet light is 230nm, we can use the photometric measurement mode to measure the absorbance of the wavelength of GOTO of the UV-Vis spectrophotometer instrument to 230nm of the maximum absorption peak of the amino acid. Amino acid content. However, because of the amino acid analysis, it is generally dissolved in water, and water has many interference absorption lines around 230 nm. Therefore, when using the UV-Vis spectrophotometer for amino acid analysis, care should be taken to prevent interference. In addition, it should be noted that only a small number of amino acids have UV absorption, and most amino acids have no UV absorption or weak, and are measured after derivatization. 4. Application in the analysis of sugars The UV-Vis spectrophotometer is mainly used for quantitative analysis in the analysis of sugar. Since the main absorption wavelength of sugar to ultraviolet light is 218 nm, when analyzing the sugar, the wavelength of GOTO of the ultraviolet-visible spectrophotometer instrument can be measured at 218 nm of the maximum absorption peak of the amino acid as long as the photometric measurement mode is used. The absorbance is calculated to calculate the sugar content. 5. Application of polysaccharide analysis and test work UV-visible spectrophotometer in the analysis of polysaccharides, mainly for quantitative detection. Because the main absorption wavelength of the polysaccharide to ultraviolet light is 206 nm, we can test the absorbance of the UV-visible spectrophotometer wavelength GOTO to the maximum absorption peak of the polysaccharide at 206 nm by using the photometric measurement mode. The content of the polysaccharide. However, the analysis of polysaccharides is very difficult. Because, at 206 nm, the energy of the light source (xenon lamp) is already weak, the energy output of the instrument optical system is also very low, the sensitivity of the photomultiplier tube is also very low, and the interference around 206 nm is also large. Therefore, the use of UV-visible spectrophotometers for the analysis of polysaccharides is very difficult, and many scientists are currently studying.

SMD/SMT Inductor(Coils)

An SMD inductor is a surface mount device inductor. It is a model of inductor that has no wire leads on its ends. This type of inductor is mounted directly to the surface of a circuit board via tining or soldering. They are positive reactance devices, available in many sizes and form factors optimized for particular applications. They are used in circuits that require filtering, power supplies, and many other functions. Inductance is associated with any PCB trace, via and ground plane and is usually considered a parasitic effect in all passive components and integrated circuits with wire bonds.ve components and integrated circuits with wire bonds.
