HPLC Method for Analysis of Inorganic anions on BIST™A+ Column

July 7, 2022

 

Separation type: Bridge Ion Separation Technology, or BIST™
 

High Performance Liquid Chromatography (HPLC) Method for Analysis of Inorganic anions, Chloride, Bromide, Nitrate, Iodide,  Perchlorate

Using SIELC’s newly introduced BIST™ method, a mixture of many different inorganic anions can be separated on a negatively-charged, cation-exchange BIST™ A column, contrary to conventional chromatographic wisdom. 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 anion analytes to the negatively-charged column surface and 2) a mobile phase consisting mostly of organic solvent (such as MeCN) to minimize the formation of a solvation layer around the charged analytes. Other positively-charged buffers that can generate BIST™ include Calcium acetate and Magnesium acetate. Using this new and unique analysis method, these anions can be separated, retained, and detected through ELSD. This method is also compatible with Mass Spectrometry.

Condition

Column BIST™ A+, 4.6×50 mm, 5µm, 100A
Mobile Phase MeCN – 90%
Buffer TMDAP ( N,N,N’,N’-Tetramethyl-1,3-diaminopropane) formate – 5 mM pH 4.0
Flow Rate 1.0 ml/min
Detection ELSD, 70C

 

Description

Class of Compounds
 Acid, Inorganic anion
Analyzing Compounds Chloride, Bromide, Nitrate, Iodide,  Perchlorate, TFA, Methanesulfonic acid

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 Method for Analysis of Iodide and Thyroid Hormones

October 30, 2018

 

Iodine is an important element in production of thyroid hormones, T3 and T4, which are essential regulators of organism’s metabolism. The glands’ concentration of Iodide, hormones T3 and T4, along with their precursors: 3,5-Diiodo-L-thyronine (T2), 3,5-Diiodo-L-tyrosine (DIT), and 3-Iodo-L-tyrosine (MIT) can now be studied simultaneously with this HPLC method.  In order to analyze the hydrophobic hormones along with iodide (a very polar inorganic ion) a special mixed-mode column, Primesep D, was used.  This column provides both strong hydrophobic and anion exchange properties.  The Primesep D silica-bonded ligand is comprised of a long alkyl chain and an embedded amino functional group.  The TFA was used as an ionic modifier to provide stable acidic pH and sufficient ion strength for the mobile phase.  The mobile phase composition is suitable for UV, MS, ELSD, and CAD detection.
