1. Principles of Ion Chromatography

Ion chromatography operates on the principle of ion exchange, where ions in the sample solution interact with a resin in the column to achieve separation. Key principles include:

1. Ion Exchange Mechanism: Sample ions displace ions bound to the stationary phase, allowing for separation based on charge and size.
2. Conductivity Detection: Ions eluted from the column are detected through their conductivity, offering high sensitivity.
3. Separation Conditions: The choice of mobile phase and flow rates is crucial to efficiently separate ions.

2. Components of an IC Ion Chromatography System
