research paper on ion exchange chromatography

Ion chromatography (or ion-exchange chromatography) is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of ...

Ion-Exchange Chromatography (IEC) allows for the separation of ionizable molecules on the basis of differences in charge properties. Its large sample-handling capacity, broad applicability (particularly to proteins and enzymes), moderate cost, powerful resolving ability, and ease of scale-up and automation have led to it becoming one of the most versatile and widely used of all liquid ...

Ion- exchange chromatography. Ion- exchange chromatography is based on electrostatic interactions between charged protein groups, and solid support material (matrix). Matrix has an ion load opposite to that of the protein to be separated, and the affinity of the protein to the column is achieved with ionic ties.

ion-exclusion chromatography, and a number of ancillary ion-based separation methods.14 In this review we focus mainly on high-performance ion-exchange chromatography coupled directly to mass spectrometry as this has been the main separation approach used with hyphenated IC-MS platforms, and the term IC-MS is often used as a synonym for "IEC ...

Abstract. Despite its inherent inefficiencies, chromatography remains the workhorse for protein purification in the pharmaceutical and biotechnology industries, with ion exchange the most widely used mode. Many aspects of a chromatographic process are still optimized empirically, but modeling is increasingly used to aid in scale-up and ...

Oligonucleotides have emerged as a promising class of pharmaceuticals, leading to significantly increased demand. Oligonucleotides are typically produced by solid-phase synthesis and then purified by ion exchange or reverse-phase chromatography. Predictive simulation is a valuable tool to help reduce process development times, secure scale-up, and decrease waste generation. In this paper, we ...

Ion exchange chromatography is a process that allows the separation of ions and polar molecules based on the charge on the surface of molecules. It is a type of solid-liquid chromatography in which the stationary phase is an ion exchange resin. It is the most popular method used for the proteins and is based on charge-charge interactions ...

Ion-exchange chromatography. It is the nature of the counterions displaced from the matrix functional groups which determines the IEC format. Thus, with anion-exchange chromatography (LHS), the stationary phase matrix displays a positively charged functional group with a negative counterion that can be displaced by an anionic sample, thereby enabling matrix adsorption.

In anion exchange chromatography, the exchanging ions are anions and the equation is represented as follow; S-X+A- + B- ↔ S-X+B-+ A- S-X + A - + B - ↔ S-X + B - + A -. The anion B - of the eluent replaced with the analyte cation A - bound to the positively charged ion X + on the surface of the stationary phase.

Introduction. Ion-exchange (IEX) chromatography is a separation method that uses charged ligands immobilized on a stationary phase to separate charged solutes fed to the column. It is the most popular method for the separation of proteins [1]. Its popularity and frequent application are due to multiple reasons:

Analytical and preparative applications from the research laboratory. Ion exchange chromatography has played a role in the purificationof thousands of enzymes, and using modern matrices with optimized separation conditions gives extremely high recoveries. Normally the isoforms of an enzyme have approximately the same molecular weight.
