  • separation
  • Agilent Technologies Inc. (NYSE: A) and CambTEK, Ltd. today announced an agreement to co-market CambTEK's Rapid Extraction System (RES) automated sample preparation technology with an assortment of Agilent's liquid phase separation, life science and chemical analysis instruments and software. (environmental-expert.com)
  • The wide range of ionic liquids that can by synthesised, with specifically tailored properties, represents a new philosophy for the separation of organic, inorganic and bio-based materials. (springer.com)
  • As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the "mobile phase") and a porous solid (the stationary phase). (wikipedia.org)
  • Gas chromatography (GC) - MS was originally introduced in 1952, when A.T. James and A.J.P Martin were trying to develop tandem separation - mass analysis techniques. (wikipedia.org)
  • chemistry
  • John Henderson Knox FRSE (born 1927) is Emeritus Professor of Physical Chemistry at the University of Edinburgh and is considered a distinguished contributor to the fields of reaction kinetics and chromatography. (wikipedia.org)
  • eluate
  • The eluate emerges as liquid phase at a flow rate of 300-500 nL/min, and any premature in-tube solvent evaporation is prevented by a convenient thermal insulation of the nebulizer and the connecting tubing from the surrounding source heat. (wikipedia.org)
  • The analyte in solution is introduced from a direct inlet probe or a liquid chromatography (LC) eluate into a pneumatic nebulizer with a flow rate 0.2-2.0mL/min. (wikipedia.org)
  • solvent
  • It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. (wikipedia.org)
  • high
  • Stein S. (1982) High-Performance Liquid Chromatography. (springer.com)
  • With the introduction of soft ionization techniques, such as electrospray ionization and atmospheric pressure chemical ionization, low molecular weight molecules can be ionized in liquid phase allowing the coupling of high performance LC to MS/MS. When MS/MS is coupled with LC, the retention time adds another property to correctly identify the analyte, resulting in enhanced specificity. (aacc.org)
  • The use of micelles in high performance liquid chromatography was first introduced by Armstrong and Henry in 1980. (wikipedia.org)
  • Indeed, heteroduplexes thermally less stable than their corresponding homoduplexes, will be resolved by chromatography when subjected to a sufficiently high temperature. (wikipedia.org)
  • High Performance Liquid Chromatography: Fundamental Principles and Practice. (wikipedia.org)
  • The nebulization is accomplished by pumping a liquid sample at moderately high pressure through an electrothermally heated capillary tube. (wikipedia.org)
  • polymer
  • In the case of UCST polymers, above the Berghmans point the phases separate into two liquid phases, below this point into a liquid polymer-poor phase and a vitrified polymer-rich phase. (wikipedia.org)
  • technique
  • The research that appeared to spark an onslaught of modified applications was a gel permeation chromatography technique of fixing poly(isopropyl acrylate) (PIPA) strands to glass beads and separating a mixture of dextrans, which was developed by Gewehr et al. (wikipedia.org)
  • commonly
  • While the mobile phase in a LC system is a pressurized liquid, the MS analyzers commonly operate under vacuum (around 10−6 torr). (wikipedia.org)
  • Knox's work over this period included development of the Knox Equation, now used commonly to describe the spreading of a solute into bands in liquid chromatography. (wikipedia.org)
  • pneumatic
  • The vapour so produced acts as a nebulizing 'gas' and aids the breakup of the liquid stream into droplets, in a process similar to pneumatic nebulization. (wikipedia.org)
  • porous
  • Back home in 1969, he published a landmark paper with Mohammed Saleem, which suggested that the highest speed in liquid chromatography would be obtained by using 2 micron porous particles. (wikipedia.org)
  • system
  • PerkinElmer, Inc., a global leader focused on the health and safety of people and the environment, today introduced the new FlexarTM liquid chromatography (LC) platform, which will be controlled by the new Chromera® Chromatography Data System (CDS). (environmental-expert.com)
  • Overall, the interface is a mechanically simple part of the LC-MS system that transfers the maximum amount of analyte, removes a significant portion of the mobile phase used in LC and preserves the chemical identity of the chromatography products (chemically inert). (wikipedia.org)
  • phase
  • After removing the liquid phase, the analytes would desorb from the belt and migrate to the MS ion source to be analysed. (wikipedia.org)
