When a beam of light passes through a certain substance (usually a solution), the substance absorbs part of the light energy. Absorbance measures how much light a substance (like a solution) absorbs. This principle is widely used to determine substance concentration via the Lambert-Beer Law. By using a spectrometer on known concentration samples, a calibration curve can be created to measure unknown concentrations. Spectrometer testing is simpler and more efficient than traditional methods, reducing human error and streamlining procedures. These devices are modular, allowing for configuration changes to meet evolving experimental needs.
