Description
Dowex® 50 W X 2 is a strong-acid cation-exchange resin in the H+-form with a defined 100–200 mesh particle range (CAS 12612-37-2). It is intended for laboratory ion chromatography and related ion-exchange separations used in environmental analysis and general chromatography workflows. The controlled mesh size supports uniform column packing and consistent exchange behaviour when processing aqueous samples. This grade from manufacturer Carl ROTH is positioned for applications that require the hydrogen form of a polystyrene-based cation exchanger. Typical laboratory uses include sample preparation, selective retention of cationic species and subsequent elution under controlled ionic-strength conditions. The resin integrates readily into standard ion-chromatography setups and supports reproducible handling when conditioned according to established ion-exchange practice. Its catalogue placement under ion chromatography and environmental analysis reflects its role in analytical and preparative separation tasks where a defined mesh H+-form exchanger is required.

Questions about Dowex® 50 W X 2, 100-200 mesh, H+-form, 100 g, plastic
What is this article?
Dowex® 50 W X 2, 100-200 mesh, H+-form, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
