  • analyte
  • In the conventional moving bed technique of production chromatography the feed entry and the analyte recovery are simultaneous and continuous, but because of practical difficulties with a continuously moving bed, simulated moving bed technique was proposed. (wikipedia.org)
  • The analyte is the substance to be separated during chromatography. (wikipedia.org)
  • In the case of an optimal system the signal is proportional to the concentration of the specific analyte separated. (wikipedia.org)
  • liquids
  • Whereas liquids are nearly incompressible, so their densities are constant regardless of pressure, supercritical fluids are highly compressible and their physical properties change with pressure - such as the pressure drop across a packed-bed column. (wikipedia.org)
  • Table 2 shows density, diffusivity and viscosity for typical liquids, gases and supercritical fluids. (wikipedia.org)
  • Both by weight and volume, gels are mostly fluid in composition and thus exhibit densities similar to those of their constituent liquids. (wikipedia.org)
  • efficiency
  • With regard to efficiency it compares with simple chromatography technique like continuous distillation does with batch distillation. (wikipedia.org)
  • Power generation systems that use traditional air Brayton and steam Rankine cycles can be upgraded to sCO 2 to increase efficiency and power output. (wikipedia.org)
  • It presents interesting properties that promise substantial improvements in system efficiency. (wikipedia.org)
  • polymers
  • Materials mimicking animal mucosal tissues to be used for testing mucoadhesive properties of drug delivery systems Common ingredients include polyvinyl alcohol, sodium polyacrylate, acrylate polymers and copolymers with an abundance of hydrophilic groups. (wikipedia.org)
  • Compounds
  • The system can be used for simultaneous achiral and chiral analysis of pharmaceutical compounds. (patents.com)
  • It is used to separate one chemical compound or one class of chemical compounds from one or more other chemical compounds to provide significant quantities of the purified or enriched material at a lower cost than could be obtained using simple (batch) chromatography. (wikipedia.org)
  • gels
  • Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. (wikipedia.org)
  • This internal network structure may result from physical bonds (physical gels) or chemical bonds (chemical gels), as well as crystallites or other junctions that remain intact within the extending fluid. (wikipedia.org)
  • substantially
  • Chromatography technique developed substantially as a result of the work of Archer John Porter Martin and Richard Laurence Millington Synge during the 1940s and 1950s, for which they won the 1952 Nobel Prize in Chemistry. (wikipedia.org)
  • Mass
  • He is a co-founder of Torion Technologies, which markets a hand-portable gas chromatography-mass spectrometry system. (wikipedia.org)
  • Starting in the 1970s Smith published peer-reviewed papers on several subjects, including mass spectrometry, ion cyclotron resonance mass spectrometry, ion-molecule reactions, molecular assemblies, and supercritical fluid solutions. (wikipedia.org)
  • techniques
  • Considerable progress has been made in both adsorption measurement techniques and molecular simulation of adsorption on computers, rendering new insights into the nature of supercritical adsorption. (wikipedia.org)
