John Knox was an early leader in the field of gas chromatography. As a PhD student in at Pembroke College, Cambridge, [3] in 1953 Knox, together with his fellow student Howard Purnell, constructed a self-designed gas chromatographer in their lab and used this to pioneer early research in the field. In later experiments Knox was the first to use ...
The history of chromatography spans from the mid-19th century to the 21st.Chromatography, literally "color writing", [1] was used—and named— in the first decade of the 20th century, primarily for the separation of plant pigments such as chlorophyll (which is green) and carotenoids (which are orange and yellow).
Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme
Erika Cremer (20 May 1900, Munich – 21 September 1996, Innsbruck) was a German physical chemist and Professor Emeritus at the University of Innsbruck [1] who is regarded as one of the most important pioneers in gas chromatography, [1] as she second conceived the technique in 1944, [1] after Richard Synge and Archer J.P. Martin in 1941.
Mikhail Tsvet invented chromatography in 1900 during his research on plant pigments. He used liquid-adsorption column chromatography with calcium carbonate as adsorbent and petrol ether/ethanol mixtures as eluent to separate chlorophylls and carotenoids. The method was described on 30 December 1901 at the XI Congress of Naturalists and ...
The first on-line coupling of gas chromatography to a mass spectrometer was reported in the late 1950s. [4] [5] An interest in coupling the methods had been suggested as early as December 1954, [6] but conventional recording techniques had too poor temporal resolution.
Fred McLafferty was born in Evanston, Illinois in 1923, but attended grade school in Omaha, Nebraska, graduating from Omaha North High School in 1940. [8] The urgent requirements of World War II accelerated his undergraduate studies at the University of Nebraska; he obtained his B.S. degree in 1943 and thereafter entered the US armed forces.
