Spectrophotometer
A spectrophotometer is an instrument that measures how much light a substance absorbs or transmits at different wavelengths, providing detailed insights into its chemical composition. In modern applications, it's indispensable for tasks like drug development in pharmaceuticals or environmental monitoring, where even tiny variations in light absorption can reveal hidden contaminants or molecular structures.
Did you know?
The first practical spectrophotometer, developed by American chemist Arnold O. Beckman in 1940, was initially created to measure pH in industrial processes but quickly transformed biochemistry by accurately quantifying proteins, aiding in the discovery of the structure of DNA. Today, these instruments are used on spacecraft like NASA's Curiosity rover to analyze Martian rocks, helping us understand if life could exist on other planets.
