A UV-VIS spectrophotometer is a scientific instrument used to measure the absorption of light by molecules in a sample. It works on the principle that when light passes through a solution, some wavelengths are absorbed while others are transmitted. The instrument measures the amount of light absorbed at different wavelengths and calculates the absorbance spectrum of the sample.
Where To Use Uv-vis Spectrophotometer
UV-VIS spectrophotometers are used in various industries such as pharmaceuticals, chemicals, and biotechnology for qualitative and quantitative analysis of samples. They can be employed to analyze the purity of compounds, measure the concentration of substances, and identify unknown substances.
