GlossarySpectrophotometry

technique measuring light absorption to determine substance concentration

Spectrophotometry is a technique used to measure how much light a substance absorbs at different wavelengths. By shining light through a sample and detecting the intensity of light that passes through, scientists can determine the concentration of specific molecules in the sample. This method is widely used in fields like chemistry, biology, and medicine to analyze the composition of various substances.
