The Thermo Scientific™ IonPac™ NS2 is a unique silica based reversed-phase column designed for mobile-phase ion chromatography (MPIC) and compatibility with suppressed conductivity detectors.

MPIC is a technique where a moderately-hydrophobic MPIC agent in the eluent provides retention for oppositely-charged analyte ions on a hydrophobic column, and then the agent is removed by the suppressor to provide selective, sensitive detection of the analytes.

The separation of moderately to strongly hydrophobic organic ions such as ionic surfactants, quaternary amines and sulfonic acids, or the separation of multiple-charged ions requires MPIC for successful separation. Under standard reversed-phase conditions, the separation is very challenging. Most ion chromatography columns were designed for small hydrophilic ions, and may not work well with hydrophobic ions. This column can provide the performance, reliability, resolution and needed versatility to achieve the separation.
