Atomic Spectroscopy
Atomic spectroscopy is a scientific technique that examines the electromagnetic radiation emitted or absorbed by atoms to identify and quantify elements in a sample. It provides precise insights into atomic structures and compositions, making it essential for modern analytical chemistry, from detecting pollutants in environmental testing to verifying purity in pharmaceutical manufacturing.
Did you know?
Atomic spectroscopy was instrumental in discovering the element helium in 1868 when French astronomer Pierre Janssen and British scientist Norman Lockyer independently observed its spectral line in the sun's atmosphere, making it the first element identified outside Earth. This breakthrough not only expanded the periodic table but also paved the way for spectroscopy to detect over 90% of known elements in various cosmic bodies.
