  • Chemist
  • The word gel was coined by 19th-century Scottish chemist Thomas Graham by clipping from gelatine. (wikipedia.org)
  • The earliest use of chromatography-passing a mixture through an inert material to create separation of the solution components based on differential adsorption-is sometimes attributed to German chemist Friedlieb Ferdinand Runge, who in 1855 described the use of paper to analyze dyes. (wikipedia.org)
  • Ion chromatography was originally introduced by two English researchers, agricultural Sir Thompson and chemist J T Way. (wikipedia.org)
  • proteins
  • An important group of biofilm matrix-associated proteins are those that polymerize into fibers variously known as pili or fimbriae ( 9 ). (pnas.org)
  • Based on phage adsorption, phage plaque formation, affinity chromatography, and Western blot assays, the outer membrane proteins of Y. pestis Ail and OmpF were identified to be involved, in addition to the rough lipopolysaccharide, in the adsorption of Yep-phi. (asm.org)
  • The phage tail fiber protein specifically interacts with Ail and OmpF proteins, and residues 518N, 519N, and 523S of the phage tail fiber protein are essential for the interaction with OmpF, whereas residues 518N, 519N, 522C, and 523S are essential for the interaction with Ail. (asm.org)
  • temperature
  • The rotation angle that must be imparted to the right or to the left to the polarimeter's Nicol analyser charged with a substance to test optically active represents, in determinate experimental conditions (type of light, temperature of experiment, conditions of brightness), a fixed constant characteristic of the substance in examination. (shroud.com)
  • High temperature headspace extraction of all standards and samples was done with an SPME fiber, which was then directly desorbed into the GC-MS system. (sigmaaldrich.com)
  • High temperature heated headspace was chosen based on previously published work, in which a 50/30 µm Divinylbenzene/Carboxen/Polydimethylsiloxane (DVB/CAR/PDMS) fiber was used 3 . (sigmaaldrich.com)
  • analysis
  • Intra- and intermolecular cross-linking were distinguished by tandem mass spectrometry analysis on fibers seeded from solutions containing equal amounts of 14 N- and 15 N-labeled protein. (pubmedcentralcanada.ca)
  • According to historical analysis of L. S. Ettre, however, Runge's work had "nothing to do with chromatography" (and instead should be considered a precursor of chemical spot tests such as the Schiff test). (wikipedia.org)

  • Chromatography can be described as a mass transfer process involving adsorption. (wikipedia.org)
  • Since 1935, ion exchange chromatography rapidly manifested into one of the most heavily leveraged techniques, with its principles often being applied to majority of fields of chemistry, including distillation, adsorption, and filtration. (wikipedia.org)
