"Ion Exchange Column"

Supplier: Cytiva

HiScreen Capto S columns are prepacked with Capto S ion exchange chromatography medium, and are part of the process development platform available from Cytiva. The columns are an excellent choice for method optimization and parameter screening.

Supplier: Resonac

SEC is the main separation mode. Depending on the eluent selected, the column adds multimode features of reversed phase, HILIC and ion exchange modes to SEC.

Supplier: VARIAN

PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation exchange functionality. The manufacturing process is controlled to provide optimum density of strong cation-exchange moieties for analysing, separating, and purifying a wide range of biomolecules from small peptides to large proteins.

Supplier: VARIAN

The PL-SAX media are well suited for anion exchange HPLC separations of proteins, peptides, and deprotected synthetic oligonucleotides. Denaturing conditions of temperature, organic solvent, and high pH levels are used for the oligonucleotide separations.

Supplier: EDVOTEK

Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of 2 chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.

In this experiment, students purify the restriction enzyme, Eco RI. This procedure utilised an ion exchange chromatograph step for Eco RI purification. Column fractions are assayed for the enzyme using Lambda DNA and digestion products are identified by gel electrophoresis. Fractions that contain Eco RI are identified and pooled. The total and specific activities are calculated. Recommended for advanced courses.

Supplier: Avantor

Avantor® Partisil® was one of the first commercially available irregular silicas. A large surface area gives it a high loading capacity. Avantor® Partisil® ion-exchange materials are widely referenced and remain one of the most popular choices for analysts.
