WebFeb 28, 2024 · The pairs formed between the analytes and reagent ions behave like neutral, hydrophobic moieties that can be separated on C18 or C8 columns. IPC is used for the separation of polar organic acids, bases and zwitterions as well as inorganic ions. Ion pairing reagents are also known as ion pairing additives or hetaerons. WebThe idea is that spectra are measured at intervals of 1 second or less during separation by HPLC with continuous eluate delivery. If the measurement is performed at a fixed wavelength, components are identified from only their retention time; thus, a minor deviation in retention time can make identification of components difficult. ...
