Application Column

Newcrom B

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

HPLC Analysis of Azide Ion on Obelisc N Column

July 10, 2012


Sodium azide is used in older car airbag systems and airplane escape slides. It is an acutely toxic substance. Obelisc N mixed-mode column can retain the azide ion using MS-compatible mobile phase of acetonitrile (ACN) and water with Ammonium Acetate as buffer. Can also be UV detected at 250nm.

Condition

Column Obelisc N, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 85/15%
Buffer AmAc pH 5- 10 mM
Flow Rate 1.0 ml/min
Detection UV, 250 nm

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.

Retention of Azide Ion on Obelisc N Column

March 13, 2012

Sodium azide is a salt of weak hydrazoic acid with pKa 4.5-4.7.
Sodium azide is very toxic. It is typically used as a stabilizer for aqueous solution to suppress bacteria grows.
Chromatography separation is based on weak ionic interaction of the partially ionized hydrazoic acid with positively charged column surface. Additional polar interaction is a result of high acetonitrile concentration in the mobile phase.
