"Ion Exchange Column"

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 two chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.

HiScreen™ SP HP columns are prepacked with SP Sepharose™ High Performance ion exchange chromatography media of 4,7 ml volume and bed height of 10 cm make HiScreen™ columns excellent tools for method optimization, parameter screening, robustness testing, and convenient scale-up.

Supplier: Thermo Fisher Scientific

These columns offer a unique HILIC selectivity and low ion exchange activity. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Bond Elut™ Mycotoxin is a novel sorbent which cleans up food extracts for improved trichothecene and zearalenone analysis. Results are comparable or superior to competing methods, including immunoaffinity columns (IaC) and charcoal/alumina columns. The sorbent is a proprietary silica-based ion exchange material.

Supplier: EDVOTEK

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.

These PEEK sample loops contain no metals or other extractable compounds. Therefore, no foreign materials will be introduced into the system. Softener free PE caps are used to avoid the contamination of the tubing. Particularly suited for separations involving proteins, peptides, nucleic acids or other samples of biological origin as well as in IC systems where metal traces may interact with ionic samples or release transition metals that may deactivate ion exchange columns.
