  • It uses a hydrophobic stationary phase and a mobile phase with varying hydrophobicity depending on the ratio of polar and organic solvent. (bitesizebio.com)
  • Methanol is more polar than acetonitrile and, hence, is less powerful in separating compounds with stronger affinity for the stationary phase. (bitesizebio.com)
  • Since the stationary phase is hydrophilic in this technique, and the mobile phase were a-polar, consisted of non-polar organic solvents such as hexane and heptane, biomolecules with hydrophilic properties in the sample had high affinity to the stationary phase, therefore they adsorb to it strongly. (wikipedia.org)
  • At the same time hydrophobic molecules experience less affinity to the polar stationary phase, and elute through it early with not enough retention. (wikipedia.org)

  • Some stationary phases are also made of hydrophobic polymeric particles, or hybridized silica-organic groups particles, for method in which mobile phases at extreme pH are used. (wikipedia.org)
  • It is typically used for separation of proteins, because the organic solvents used in normal-phase chromatography can denature many proteins. (wikipedia.org)
  • Improve the separation by tweaking the concentration of the ion-pairing agent, the percentage of organic solvent and pH of the mobile phase. (bitesizebio.com)
