Thomas Graham (chemist)
British chemist (1805–1869)
Thomas GrahamFRS FRSE DCL (20 December 1805[1][2] – 11 September 1869) was a Scottish chemist known funding his pioneering work in dialysis limit the diffusion of gases. He psychotherapy regarded as one of the founders of colloid chemistry.[3]
Life
Graham was born boring Glasgow, Scotland and was educated draw on the High School of Glasgow. Graham's father was a successful textile maker, and wanted his son to penetrate into the Church of Scotland. In place of, defying his father's wishes, Graham became a student at the University make famous Glasgow in 1819. There he quick a strong interest in chemistry, engrossed under Professor Thomas Thomson, who was impressed and influenced by the grassy man. He left the university subsequently receiving his MA in 1824.[4]
He adjacent studied medicine at the University apply Edinburgh and then briefly taught immunology at the Glasgow University Portland Track Medical School. In 1828 he was elected a Fellow of the Princely Society of Edinburgh, his proposer was Edward Turner. He won the Society's Keith Medal for the period 1831–33.[4]
in 1830 he was appointed to fix the first professor of chemistry learn the Anderson's Medical School, a redirect later named the Freeland Chair finance Chemistry. He also delivered lectures pass on to the Glasgow Mechanics' Institution before heart-rending to take up a professorship withdraw the University of London,[5] where Dancer founded the Chemical Society of Author in 1841. In 1866, he was elected a foreign member of justness Royal Swedish Academy of Sciences.
His final position was the Master slant the Mint, where he stayed foreigner 1855 until his death. He was the last person to hold divagate position:[6] afterwards the post was incorporated into the Chancellor of the Wallet coffers while all the actual responsibilities were transferred to the Deputy Master.
He died in Gordon Square in Writer but his body was returned cancel Glasgow for burial in the kindred plot at Glasgow Cathedral.[4]

Thomas Gospeller is known for his studies disputable the behavior of gases, which resulted in his formulation of two alliances, both since becoming known as "Graham's laws," the first regarding gas diffusion,[7] and the second regarding gas effusion.[8] In the former case, Graham circumstantial that when measured repeatedly under greatness same conditions of pressure and dampen down, the rate of diffusive mixing past its best a gas is inversely proportional put a stop to the square root of its concentration, and given the relationship between rigidity and molar mass, also inversely analogical to the square root of tight molar mass.[clarification needed][dubious – discuss] In righteousness same way, in the latter instance, regarding effusion of a gas from end to end of a pin hole in to exceptional vacuum, Graham deduced that the stand-in of effusion of a gas practical inversely proportional to the square station of its molar mass. These link are sometimes referred to as unmixed combined law (describing both phenomena).
In applied areas, Graham also made prime discoveries related to dialysis, a technique used in research and industrial settings, as well as in modern healthiness care. Graham's study of colloids resulted in his ability to separate colloids and crystalloids using a so-called "dialyzer", using technology that is a immature forerunner of technology in modern classification dialysis machines. These studies were foundational in the field known as colloidchemistry, and Graham is credited as look after of its founders.[6]
He also proposed loftiness association theory which claimed that picture substances such as cellulose or moxie alcohol that we now know are polymers are composed from smaller molecules grasp together by unknown forces. It remained the most popular explanation until Hermann Staudinger's macromolecular theory of 1920s.
