HPLC Application of HILIC Retention of 1,5-Naphthalenedisulfonic Acid on Obelisc N Mixed-Mode HILIC Columns  Naphthalenedisulfonic acid is retained by anion-exchange mechanism on Obelisc N mixed-mode HILIC column. Retention time is controlled by amount of ion in the mobile phase. Method demonstrates very good peak shape and controllable retention. This mixed-mode approach can be used for quantitation of various sulfonic acid in different matrices. UV, ELSD or LC/MS can be used for quantitation. Application Analytes: Sulfonic Acid 1,5-Naphthalenedisulfonic Acid Application Detection: UV Detection ELSD/MS Detection |
