Georg Ludwig Carius (born August 24, 1829 in Barbis , Kingdom of Hanover , † April 24, 1875 in Marburg ) was a German chemist .

He lost his parents in early childhood and the pastor Gehring took care of him. After graduating from the school in Goslar, he went the pharmacist Dempwolf into teaching . Here he decided, despite seemingly insurmountable difficulties, to study chemistry in Göttingen .

From 1850 to 1852 he studied with Friedrich Wöhler in Göttingen . From 1852 to 1858 he was an assistant at the Heidelberg University Laboratory . He took part in Robert Wilhelm Bunsen's physico-chemical studies of gases , received his doctorate in 1853 and, after completing his habilitation in 1857, was a private lecturer in Heidelberg . In 1861 he became an associate professor and in 1865 a full professor of chemistry at the University of Marburg . In 1860, Carius developed a method for the quantitative determination of halogen , sulfur and phosphorus in organic compounds, which is based on oxidation with fuming nitric acid in a sealed, thick-walled bomb tube (English: Carius tube ) and the subsequent gravimetric determination of the halides , sulfates and phosphates formed in this way . He is also known from his textbook on polybasic acids.
