The light source generates ultraviolet, visible and near-infrared light, which passes through the sample in the cuvette. The residual light absorbed by the sample is dispersed by the monochromator and received by the detector, so as to analyze the sample qualitatively and quantitatively, and to identify the purity and structure of the sample.
UV-Vis-NIR (Ultraviolet-Visible-Near Infrared) Spectrophotometer (UV-Vis-NIR), whose scanning wavelengths cover the ultraviolet, visible, and near-infrared regions, utilizes the absorption characteristics of material molecules on ultraviolet, visible, and near-infrared light for quantitative and qualitative analysis, and it is one of the common instruments in scientific research laboratories as well as in industrial fields.
UV-visible-near-infrared spectrophotometer is a kind of spectrophotometer products, the spectral range of spectrophotometer mainly includes 200-380nm ultraviolet region, 380-780nm visible region, 760nm-1mm infrared region, the corresponding products include ultraviolet spectrophotometer, visible spectrophotometer, infrared spectrophotometer. The UV-Visible-NIR spectrophotometer integrates the functions of the above three spectrophotometers into one, and has a wider range of use.
UV-VIS-NIR spectrophotometer is mainly composed of light source, sample cell, monochromator, detector and so on. The light source produces ultraviolet light, visible light, near-infrared light, through the sample in the sample cell, the sample after absorption of the remaining light through the monochromator dispersion, is received by the detector, so as to qualitatively and quantitatively analyze the samples, and the purity of the samples, the structure of the identification.
The scanning band of UV-VIS-NIR spectrophotometer is between 175-3300nm, generally 200-2500nm, which can measure organic and inorganic substances, and can carry out non-destructive testing of liquid and solid materials, and it has the advantages of high sensitivity, high resolution, wide measurement range, fast measurement speed, high analytical accuracy, and low sample dosage.
According to the "2023-2028 China UV-Vis-NIR Spectrophotometer (UV-Vis-NIR) Industry Market Depth Research and Development Prospect Forecast Report" released by Xinsiye Industry Research Center, UV-Vis-NIR spectrophotometer can analyze the composition, purity, molecular structure, and content of each component of the material and other parameters, and can be applied in biology, chemistry, materials science, optics, physics and other fields. It can be applied in biology, chemistry, material science, optics, physics and other disciplines, and can be widely used in electronics, communications, petroleum, chemical industry, metallurgy, medicine, food, agriculture, geology, environmental protection and other fields.
Globally, the main manufacturers of UV-VIS-NIR spectrophotometers are Shimadzu, Japan (Shimadzu), Hitachi, Japan (Hitachi), Japan Spectroscopy (JASCO), Agilent, the United States (Agilent Technologies), the United States, Perkin Elmer, Switzerland, METTLER TOLEDO (METTLER TOLEDO). METTLER TOLEDO), India Labindia Instruments (has been acquired by the U.S. AB SCIEX) and so on.
Xinsiye industry analysts said that at present in China's spectrophotometer market, common products are mainly ultraviolet-visible spectrophotometer (UV-Vis), ultraviolet-visible-near-infrared spectrophotometer share accounted for a relatively small amount, but the measurement range is more extensive, with new materials, new medicines, and other products continue to be developed and come out, has a good prospect for development. Spectrophotometer has certain technical barriers, in China's market, foreign enterprises occupy a competitive advantage, the domestic enterprise production strength has gradually increased, but mainly concentrated in the low-end market competition.
