Description
A spectrophotometer is an instrument used to measure the amount of light absorbed or transmitted by a sample based on wavelength. It is a tool commonly used in various fields, such as chemistry, biochemistry, physics, and materials science.
The basic operation of a spectrophotometer is based on the Beer-Lambert law, which states that the amount of light absorbed by a solution is directly proportional to the concentration of the substance present in the sample. The spectrophotometer measures the amount of light absorbed by a sample at different wavelengths and provides an absorption or transmittance spectrum.
The instrument consists of a light source, a single-component or multi-component system for selecting different wavelengths of light, a sample sample, and a detector for measuring the intensity of transmitted or absorbed light. The results are shown in a graph called a spectrum, which shows how the sample interacts with light as a function of wavelength.
The spectrophotometer is used in various applications, such as the analysis of chemical components in liquid samples, the determination of concentrations of substances in solutions, the analysis of the composition of food and beverages, quality control in the pharmaceutical industry, among others. It is a very versatile tool and widely used in scientific research and analysis.
