TEMIZ™ DVB-SAX MP

DVB-SAX MP

Material overview

TEMIZ DVB-SAX MP Resin are polymeric resins based on highly stable DVB-Styrene or intermediate polar methacrylate resins with strong anion exchange (SAX) quaternary amine Chloride groups.

Typical properties of the resins are:

Porosity: mesoporous – optimal for small molecules
Cross-linking: moderate cross-linkage
Particle size: ca 200 – 1200 µm
Capacity variations: ca 1,4 – 4 mmol/ml (dry resin)

The resins are characterized by its good rigidity and high loading of quaternary amine chloride groups.

Table of properties of the 9 SAX resin variants in-house.

Resin	Backbone	Capacity dry meq/g
SAX001	Styrenic	2,0
SAX002	Styrenic	1,9
SAX003	Styrenic	2,9
SAX004	Acrylic	1,4
SAX005	Styrenic	2,2
SAX006	Styrenic	2,5
SAX007	Styrenic	4,0
SAX008	Acrylic	3,0
SAX009	Acrylic	2,1

Some resins have a styrenic backbone and some a acrylic backbone, they differ in capacity and also resin architecture. Those differences can give tremendously different results depending on the application. It is well known that resins with similar basic specifications can behave very differently for a given application. Therefore, it is wise and highly recommended to test a library of promising candidate resins to evaluate for a given separation challenge.

Applications

The strong functional group is effective as a conventional ion exchange resin or scavenger. The relatively small pore size is optimal for small molecules and the resin will exclude large molecules like proteins or other large molecular complexes.

Typical uses for strong anion exchangers are for binding to opposite charged ionic species in various types of solutions including pharmaceutical mixtures or biological extracts or plant-based extracts.

SAX resins can bind and scavenge out the following compound types

Phenolics
Organic acids, phosphates
Inorganic anions
Biological molecules with acidic groups

One recent example of ours is on the reduction of undesired polyphenolic compounds in industrial potato fruit juice. Interestingly, the best performing resin was SAX002, even though other SAX resins in the collection with similar or higher capacity and with the same styrenic backbone were tested. Hence, resin architecture is an overlooked and important factor in separation science, but must be determined by experimental tests for each matrix. Ie, every complex solution may need to be screened with a library of promising resins to determine the best performing candidate for a given separation challenge.
