Applications:


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:

1,5-Naphthalenedisulfonic Acid
Sulfonic Acid

HPLC Separation of Organic Acids in HILIC and Anion-Exclusion Mode on Primesep S2 Column
