Spectrophotometer, also known as spectrometer, is a commonly used analytical instrument for qualitative and quantitative analysis of the substance by measuring the absorbance of light at a specific wavelength or a certain wavelength range.
Spectrophotometer comes in many varieties and uses. Visible spectrophotometers are mainly used in chemical analysis such as metallurgy, medicine, food industry, medicine, health, chemical, school, biochemistry, petrochemical, quality control, environmental protection and scientific research laboratories. It is a single-beam spectrophotometer that measures the absorbance of visible light (400-760 nm) of a substance to be tested and qualitatively and quantitatively analyzes it.
The atom first absorbs the spectrophotometer source and then emits the measured characteristic spectrum radiation. It is absorbed by the ground state atoms of the element to be tested in the sample vapor after passing through the atomizer. The content of the element to be measured is determined by measuring the magnitude of absorption of the characteristic radiation. It is one of the conventional instruments for the analysis laboratory of production, education and scientific research units.
The UV-Vis spectrophotometer is used to measure the absorbance of the sample to visible or ultraviolet light (200-760 nm) and to qualitatively and quantitatively analyze it. It has been widely used in the fields of drug analysis, drug testing, sanitary and epidemic prevention foods, environmental testing, chemical engineering, scientific research, etc. It is an indispensable instrument for production, scientific research and teaching.
