ion-pair chromatography

(IPC) -  form of liquid chromatography in which ions in solution can be "paired" or neutralized and separated as an ion pair on a reversed-phase column.

Ion-pairing can also occur in normal-phase chromatography when one part of the pair is loaded onto a sorbent, but this technique is not as popular as the RPC technique.

The term "ion-pair chromatography" was found in the following pages:
