  • We discussed how different methods of preparing eluents composed of acetonitrile and aqueous components can lead to very different retention times and selectivities, and that we can help our colleagues by providing more detail when documenting eluent preparation procedures, whether for standard operating procedures (SOPs) or journal articles. (chromatographyonline.com)
  • As a practical matter, then, we are faced with the question of whether it is the pH of the aqueous buffer used in the eluent that matters, or the pH of the aqueous-organic mixture. (chromatographyonline.com)
  • In other words, if we are aiming to use an ammonium acetate buffer at pH 6, should we determine that pH in the aqueous component of the eluent before mixing it with acetonitrile or after mixing? (chromatographyonline.com)
  • Steric recognition of very similar substances like isomers is possible with YMC-Triart C18 ExRS, while there is no limit to usage of 100% aqueous eluents on YMC-Triart C18. (laboratory-journal.com)
  • proteins
  • The separated proteins are continuously eluted into a physiological eluent and transported to a fraction collector. (wikipedia.org)
  • liquid
  • NOVELTY - The repairing method of halogenated hydrocarbon contaminated sites by using combination of chemical leaching and microbial involves performing chemical leaching, injecting eluent into contaminated soil via injection wells, withdrawing eluent carrying contaminantes from extraction wells, dissolving biosurfactants in carrier liquid, rinsing eluent, and injecting KB1 bacteria into contaminated soil for carrying out microbial remediation.

  • method
  • Finally, method development approaches are discussed and pragmatic, simple method development platforms are illustrated based upon rational phase and eluent choice. (rsc.org)
