High Performance Liquid Chromatography (HPLC) Method for Analysis of  2 – Naphthalenesulfonic acid and 1,5-Naphthalenedisulfonic acid

2-Naphthalenesulfonic acid and 1,5-Naphthalenedisulfonic acid, also known as Armstrong’s acid, are two similarly-structured compounds. 2-Naphthalenesulfonic acid is commonly used in dye production and 1,5-Naphthalenedisulfonic acid is used in synthesizing the salts of basic drugs and in electrokinetic chromatography. Using SIELC’s newly introduced BIST™ method, these two acids can be retained on a negatively-charged, cation-exchange BIST™ A column. There are two keys to this retention method: 1) a multi-charged, positive buffer, such as N,N,N’,N’-Tetramethyl-1,3-propanediamine (TMDAP), which acts as a bridge, linking the negatively-charged tartrazine analytes to the negatively-charged column surface and 2) a mobile phase consisting mostly of organic solvent to minimize the formation of a solvation layer around the charged analytes. Using this new and unique analysis method, 2-Naphthalenesulfonic acid and 1,5-Naphthalenedisulfonic acid can be retained and UV detected at 270 nm.

Application Column

BIST A

BIST™ columns offer a unique and effective way to achieve separations that were traditionally challenging or even impossible with other HPLC columns. With the use of a special mobile phase, these ion exchange columns provide very strong retention for analytes with the same charge polarity as the stationary phase, unlocking new chromatography applications. What makes BIST™ columns stand out is their proprietary surface chemistry, which results in superior selectivity, resolution, and sensitivity. These columns offer a simple, efficient solution for a variety of analytical challenges, making them an excellent choice for researchers and analysts across many different fields.

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

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.

Application Column

Obelisc N

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
