Principle of Ion Chromatography

The fundamental principle behind ion chromatography involves the separation of charged species based on their interaction with a stationary phase. The sample is injected into a column containing resin beads that are selectively charged. As the sample moves through the column, ions interact differently based on their charge and size, leading to their separation. The elution of these ions is monitored using a conductivity detector, allowing for quantification.
