HPLC Determination of 1,5-Naphthalenedisulfonic Acid on Newcrom BH Column

HPLC Method for 1,5-Naphthalenedisulfonic Acid on Newcrom BH by SIELC Technologies

 

High Performance Liquid Chromatography (HPLC) Method for Analysis of 1,5-Naphthalenedisulfonic Acid.

1,5-Naphthalenedisulfonic acid is a strong organic acid with a double charge.  Multi-charged molecules generally have a tendency to exhibit poor peak shape in HPLC on reverse-phase columns showing significant tailing.  The acid can be retained with great peak shape on a Newcrom BH mixed-mode column.  The Newcrom line of columns was designed specifically for improved peak shape of multi-charged molecules.  The method uses a mobile phase consisting of acetonitrile (ACN), water and ammonium formate buffer, making the method MS-compatible.  UV detection at 260nm can also be used.
