Description
Dowex® 50 W X 8 is an ion-exchange material supplied in the H+-form at 50-100 mesh, identified by CAS number 11119-67-8. The defined mesh range supports controlled packing and flow behaviour in laboratory ion chromatography and related separation setups used in environmental analysis and analytical chemistry. This provides a practical working quantity for method development, column preparation and routine exchange steps. Available from manufacturer Carl ROTH, the product fits chromatography workflows where a strongly acidic cation-exchange resin in hydrogen form is required. Consistent particle sizing aids reproducibility when preparing columns or batch-contact experiments. Laboratories select Dowex® 50 W X 8 for sample clean-up, ion exchange and fractionation tasks that depend on a well-specified H+-form resin. Clear labelling of mesh size, ionic form and CAS supports traceable purchasing and documentation in regulated or quality-managed analytical environments.

Questions about Dowex® 50 W X 8, 50-100 mesh, H+-form, 250 g, plastic
What is this article?
Dowex® 50 W X 8, 50-100 mesh, H+-form, 250 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.
