Ion Pairing Reagents for HPLC

Ion Pairing Reagents are use as mobile phase additives, which allow the separation of ionic and highly polar substances on reversed phase HPLC columns.

The addition of Ion pairing reagent in mobile phase as a counter ion of an opposite charge, enables the sample species to form neutral ion pair which readily interact with the reverse phase packing hence permit clean separation.

Span Chemie Ion Pairing Reagents are highly pure and suitable for detection in the low UV range and inspected by means of the filter test, cyclovoltagram and gradient test
