Ion Pair Reagents



Ion Pair Reagents

Ion Pair Reagents are used for improving the chromatographic separation of polar compounds. The use of these reagents can enhance peak shape and retention time when conventional techniques, such as changing the stationary phase or altering eluent ratios, prove insufficient. Ion Pair Reagents are added to the HPLC mobile phase to promote the formation of ion pairs with charged analytes.

MilliporeSigma offers n-alkyl sulfonates with varying chain lengths that act as anionic counter-ions for improving the separation and resolution of positively charged molecules. These products feature outstanding purity and UV transparency.
