Description
Dowex® 1 X 2 is a strongly basic anion-exchange resin supplied in the chloride form with a particle size of 100–200 mesh and CAS number 9085-42-1. Materials of this type are used in ion-exchange and ion-chromatography workflows for separation, purification and sample preparation of anionic species in analytical and preparative laboratory settings. The 100–200 mesh grade offers a balance of flow characteristics and exchange surface suited to column packing and batch contact procedures. This variant is Dowex® 1 X 2 (Cl⁻-form) from manufacturer Carl ROTH is positioned for chromatography and ion-exchanger applications where a defined mesh range and chloride counter-ion are required. Clear identification by CAS and mesh specification supports reproducible packing and consistent performance across successive separations.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Dowex® 1 X 2, 100-200 mesh, Cl--form, 100 g, plastic
What is this article?
Dowex® 1 X 2, 100-200 mesh, Cl--form, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is Sorbents, silica gel & ion exchangers. The catalogue is Chromatography equipment.
