The light source generates ultraviolet light, visible light and near-infrared light, which passes through the sample in the sample pool. The residual light absorbed by the sample is dispersed by the monochromator and received by the detector, so as to conduct qualitative and quantitative analysis of the sample, and identify the purity and structure of the sample.
Ultraviolet-visible-near-infrared spectrophotometer (UV-VIS-NIR), its scanning band covers ultraviolet light, visible light, near infrared light area, the use of material molecules to UV light, visible light, near infrared light absorption characteristics to carry out quantitative and qualitative analysis, is one of the common instruments in scientific research laboratories and industrial fields.
Ultraviolet-visible-near-infrared spectrophotometer is a kind of spectrophotometer products, the spectral range of the spectrophotometer mainly includes 200-380nm ultraviolet light region, 380-780nm visible light region, 760nm-1mm infrared light region, corresponding products include ultraviolet spectrophotometer, visible spectrophotometer, infrared spectrophotometer. Ultraviolet-visible-near-infrared spectrophotometer integrates the functions of the above three kinds of spectrophotometer into one, and has a wider range of use.
Ultraviolet-visible-near-infrared spectrophotometer mainly consists of light source, sample cell, monochromator, detector and so on. The light source generates ultraviolet light, visible light and near-infrared light, which passes through the sample in the sample pool. The residual light absorbed by the sample is dispersed by the monochromator and received by the detector, so as to conduct qualitative and quantitative analysis of the sample, and identify the purity and structure of the sample.
Ultraviolet-visible near-infrared spectrophotometer scanning band between 175-3300nm, generally 200-2500nm, can measure organic substances and inorganic substances, can be nondestructive testing of liquid, solid materials, with high sensitivity, high resolution, a wide range of measurement, measurement speed, high analysis accuracy, sample consumption and other advantages.
According to the 2023-2028 China UV-Vis-Near-infrared Spectrophotometer (UV-Vis-NIR) industry Market In-depth survey and Development Prospect Forecast Report released by Xinsi Industry Research Center, UV-VIS-near-infrared spectrophotometer can analyze the composition, purity, molecular structure and the content of each component and other parameters. Can be used in biology, chemistry, materials science, optics, physics and other disciplines, 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-Visible-near-infrared spectrophotometers are, Shimadzu (Japan), HITACHI (Japan), JASCO (Japan), Agilent Technologies (United States), Perkin Elmer (United States), METTLER (Switzerland) TOLEDO, India's Labindia Instruments (acquired by AB SCIEX of the US) and others.
Xinsi industry analysts said that at present in the Chinese spectrophotometer market, the common products are mainly UV-visible spectrophotometer (UV-Vis), UV-visible near-infrared spectrophotometer share accounts for a relatively small, but its measurement range is more extensive, with the development of new materials, new medicine and other products, has good prospects for development. Spectrophotometers have certain technical barriers. In the market of our country, foreign enterprises occupy a competitive advantage, and domestic enterprises gradually strengthen their production strength, but mainly concentrate on the low-end market competition.
