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.

Sulfonic Acid

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

Organic acids were separated on a HILIC/cation-exchange column in HILIC/anion-exclusion mode. This column can be used for analysis of polar compounds in HILIC mode. If compounds are ionizable, additional mode of interaction can be added (cation-exchange or anion-exclusion).
