• In the mid-1970s, interest in liquid mobile phases for column chromatography resurfaced when it was discovered that the efficiency of separation could be vastly improved by pumping the liquid through a short packed column under pressure, rather than allowing it to flow slowly down a vertical column by gravity alone.

  • Recent successes in the use of salt mediated pH gradient ion exchange chromatography with volatile mobile phases have shown there to be significant promise in using online mass spectrometric (MS) detection to facilitate peak detection. (nih.gov)
  • It may be a liquid (LC and Capillary Electrochromatography (CEC)), a gas (GC), or a supercritical fluid (supercritical-fluid chromatography, SFC). (wikipedia.org)
  • Biochrom Ltd, a manufacturer of quality scientific instruments for applications in the life science, clinical, and analytical markets, announced today the commercial launch of its EZ Nin ReagentTM, a ready-to-use ninhydrin formulation for use in ion exchange chromatography systems with post-column derivatisation for improved amino acid analysis.

  • By introducing chromatography to Western European scientists, Willstatter helped establish one of the most versatile analytical techniques known to chemistry. (discoveriesinmedicine.com)
  • Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. (wikipedia.org)
  • Analytical chromatography is used to determine the existence and possibly also the concentration of analyte(s) in a sample . (wikipedia.org)
