2009年1月23日 · The review presents an overview of studies concerning the effect of eluent composition on the ionization efficiency of ESI, APCI and APPI in LC–MS. Solvent …

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent: washing of loaded ion-exchange resins to remove captured ions, or …

Elution Gradient elution in liquid chromatography is analogous to temperature programming in gas chromatography. Increased eluent strength is required to elute more strongly retained solutes. …

1999年9月24日 · This paper provides a general overview of flow-cell based IR detection and briefly discusses early solvent-elimination interfaces for LC–FT-IR. A more comprehensive …

2020年2月22日 · Fluorinated eluent additives aid the retention of bases, but reduce it for acids. This research focuses on retention mechanisms in a LC column with C18 stationary phase …
