IPC is a type of ion chromatography that is used to separate hydrophilic or charged analytes oncolumns using reversed phase or “neutral” stationary phases that do not carry charges. It involves modifying the polarity of the charged analytes through their interaction with an ion-pairing reagent that is … Meer weergeven The choice of ion pairing reagent is perhaps the most important parameter when using IPC. The reagent type, its concentration … Meer weergeven Although ion pairing chromatography provides certain advantages over other techniques such as IEX and normal phase chromatography, it suffers from limitations as well (Table … Meer weergeven Several modes of chromatography, such as hydrophilic interaction chromatography (HILIC) and IEX, and different types of stationary phases, such as ion exchange or polar, have been used for the separation of … Meer weergeven IPC has been applied for the analysis of a wide variety of analytes, ranging from environmental samples, pharmaceuticals and food to biological samples and metals. Meer weergeven WebThe ion-paired complex is known to be less stable than the chemically conjugated prodrug form, and a major concern when utilizing the ion-pairing approach is the possibility of premature complex dissociation in the biological fluids prior to absorption. 23 However, chemical modification by attaching a functional molecule to the drug may result in …
