Spectrophotometers are an essential tool in various industries, including pharmaceuticals, biotechnology, and chemical analysis. These instruments measure the intensity of light absorbed, transmitted, or reflected by a sample, providing valuable information on composition and concentration. Spectrophotometers can be classified into three main types: ultraviolet-visible (UV-Vis), infrared (IR), and atomic absorption (AA). When selecting a spectrophotometer, consider factors such as the sample type, measurement range, and desired accuracy. Additionally, ensure the instrument is compatible with your laboratory’s existing equipment and software. By choosing the right spectrophotometer, you can optimize your analytical workflow and achieve accurate results.
