WebIt is often resolved by disconnecting the column and rinsing the flow line with organic solvent. If a peak is completely split in two or forms a shoulder peak, gaps might have developed inside the column. In such cases, rinsing the column will not restore performance. WebIon chromatography (IC) is a widely used analytical technique for the separation and determination of anionic or cationic analytes in various sample matrices. It is performed in several separation and detection modes today. IC with suppressed conductivity detection remains the most widely practiced form of the technique.
