Description
CHROMABOND HR-XAW columns are solid-phase extraction columns featuring a weak mixed-mode anion exchanger on a polymer basis. They enable selective sample clean-up and enrichment of anionic species by combining weaker ion-exchange interactions with reversed-phase retention, which is useful when milder elution or pH-controlled recovery is preferred. Each column has a 1 mL volume with a 30 mg sorbent bed and is constructed from polypropylene with polyethylene filter elements for dependable flow and chemical resistance. Packs contain 30 pieces from manufacturer Macherey-Nagel and suit method development as well as routine SPE in analytical laboratories. The polymer-based weak mixed-mode chemistry supports work with complex matrices in environmental, food and pharmaceutical applications where strong anion exchangers may retain analytes too tightly. Columns fit standard SPE manifolds and automated systems without special hardware. Uniform bed packing and PE frits help maintain reproducible recoveries in both manual and automated protocols. This compact 30 mg format is practical for laboratories standardising weak mixed-mode anion-exchange SPE steps.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns HR-XAW, 1 mL, 30 mg
What is this article?
Chromab. columns HR-XAW, 1 mL, 30 mg is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
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?
